Pneumonoultramicroscopicsilicovalcanoconiosis is a lung disease caused by the inhalation of very fine silicate or quartz dust, causing inflammation in the lungs. Thank you for teaching me such a big, grandios term. Salute.
The lung damage caused by silica powder is permanent. SiO2 cannot be metabolized by human species, due to its incredibly stable chemical bond. It will remain in your lungs long after your death.
The force ripples through the outside to where they meet in the back where all of the shock converges into where it cracks. All accounted to its round shape.
Correct me if I’m wrong, but due to the fact that glass is so brittle, how would it “ripple”. I understand that energy must travel through it but glass doesn’t have much give to it.
The damage on the back is called "spalling". It's when the pressure waves inside the material reach the back surface, and create stresses in the material large enough to fracture. It's one of the reason armor plates have to be spall coated. There are also some anti armor weapons that use spallation to create shrapnel on the inside of an armored vehicle or structure without penetrating. The shockwave just blasts shrapnel off the backside when it propagates thorough. en.wikipedia.org/wiki/High-explosive_squash_head
since its a sphere, all the energy goes through it like a wave and then all the waves hit each other on the other side impacting each other and creates a break on the other side pretty much directly across it
It's sending energy around the edges all the way around by miniscule amounts of movement in the glass caused by the high speed of the bullet, all of that force collides with itself on the farther point from the point of impact, that being said, when you switched to the second ball and used the higher velocity shots, the force was enough to extend off the sides rather than follow around the curve. (That's why it had the large round cracks halfway through)
In a nutshell, what is happening is that the force transfers around and through the ball, until the different waves meet at the point exactly opposite the initial impact, adding themselves back together, thus making a force with both nowhere to go, and one that is too strong for the glass to hold. A really cool and interesting phenomenon.
The reason that the back is cracked is based on the shape of the sphere and how it distributes force. Arches (and spheres) apply force throughout the entire surface. The cracks are formed when the forces travel around the surface of the sphere and collide. Also, when enough force is applied to armor to cause the back to break off, it's called spalling. Not sure if it applies here though.
The British developed HESH (High Explosive Squash Head) ammunition that plastered a large amount of plastic explosive to armor plate and then detonated it with the rear of the shell after it had squashed as opposed to using the front to detonate on contact like standard HE rounds. This send a shockwave directly through the material causing it to spall on the inside when the shockwave reached the back side of the armor. With no further armor there to support it the force of the shockwave exceeds the strength of the material causing it to fail. This is likely what is occurring here rather than the shock wave traveling around the outside as the shock wave from the impact would arrive at the back much more quickly traveling directly through the center rather than around the outside much like seismic waves through the earth. In addition the other shot locations would cause the shock traveling around the outside to cause additional damage at those locations as they are flaws in the shape much like how a tin can can hold a heavy load in the axial direction until you introduce a small flaw and it collapses violently and suddenly.
@@bloodandoil9226 It only happened with the slower pistol rounds which had wider and blunter tips compared to the faster moving rifle rounds. Was able to transfer the force of the bullet through the glass instead of penetrating it.
"What is happening?" When a pebble drops into a pond, it sends out ripples, yes? On a sphere, those ripples extend outwards, across the sphere, and converge at a single point directly opposite the point of impact, creating a disturbance comparable to the original impact. This forms the crack on the back side.
From an impact like that (or any impact really), the molecules of the glass ball REALLY want to move and react, but can't due to their structure. The shockwave from the bullet can't dramatically affect the structure of the interior because the interior is simply too tough. The area that CAN be affected is the area with the weakest defense from the shockwave as it passes through: the narrowing opposite side. Think of the force like a diamond: the sharp end (the shockwave of the impact) is lessened by the interior (the thick middle) and exits the opposite side (the opposite sharp end). I think it may even be more than that, though. Waves echo through materials, through air or through solids. The shockwave might have "bounced" from the impact, to the opposite end, and back again. Right at that area of "echo", you have an area of reflection that might have created the crack. I'm thinking it's something like this in the case of the massive .44 magnum.
I like that he didn’t think anything of the ripples left behind, I wish he put a slo mo camera up in the back so we could watch it all meet and explode the back out.
if you have it sighted in for pretty long range(nothing past where the bullet is dropping), it will generally hit around as low as the distance from the center of your scope down to the center of your barrel when shot at close range.
The “counter impact” is known as spalling. The force from the bullet impacting transfers to the opposite face of the glass ball and causes it to split off or “spall”. This occurs with harder objects such as tank armor and there are specific types of ordnance known as HEP rounds that don’t penetrate armor but cause it to spall on the inside surface tearing up the inside of the tank or armored vehicle.
The glass acts this way for the same reason a newton's cradle only effects the opposite ball. The energy travels through and is released through the last bit of material. This could be better explained but iam not an educator.
Any of the excess energy from the initial impact that wasn't released through sound heat and the cracks in the ball traveled through until it hit the back and came together for a second impact
Answer for why there is a crack on the other side: This is the forensic scientists' [3R] rule-radial cracks make right angles to the rear. In a concentric crack, it's the opposite-the chonchoidal fractures DO make a right angle to the side the force came from. This can be vitally important in determining if something was a shoot-out or a shoot-in. Plz like so Matt can see this
Explanation on the little crack: When the bullet hits, it send out vibrations in all directions, and the crack is resulting from the vibrations all meeting back up on the other side. The crack should be almost exactly opposite of the initial impact.
Yepp, same with earthquakes and how we measure them. Also, thats how some major volcanoe provinces in earths history are supposed to happen at the backside of earth when an asteroid hit.
I was going to say the same thing, but didn't want to be that repeat guy. I love physics, didn't take long with a little ponder. but the physics is a little more complex than that. notice the small crack is always somewhere inside the ball. the vibrations do indeed travel in all directions, even across the surface, but the vibrations continue multiple passes around the ball before all meet together. the surface vibrations have a longer time traveling to opposite side as direct line will be shorter. therefore, the vibrations direct line head back towards the front again before surface reaches the back. my guess these vibrations bounce around a bit off of one another till enough vibrations meet together to expend energy in the breaking of the glass somewhere inside
the effect is called spalling. it happens when energy travels through an object and breaks pieces off the other side of the object. it's the principle behind HESH projectiles.
Well at least your close. The sphere actually focuses the shockwave to a point on the other side. When spalling happens in armor it's in a wider area. Same thing though lol
The momentum of the bullet is carried trough the glass and comes together at the opposite end which creates a more concentrated spot of energy which makes the glass crack
its called a conical fracture, when a spherical object made of a non-flexible material (glass, ice ,ect) is impacted it fractures in this way because the force of the impact is distributed outwards creating the cone shape and the secondary concussion creates the smaller chip/crack at the back
Also, glass is an amorphous solid so it doesn't break apart like metal or rock would. Reaction forces from amorphous solids are much different than crystalline.
In less smart words so regular people can understand, Basically the force of the bullet vibrates through the glass and when it is at the end of the sphere it pushes off into the open air wich cracks the back of the sphere.
That's vibrations what crack the ball at the other side. Essentially, when bullet hits, it creates a pressure wave, mostly on surface, because only surface can actually transmit wave, as internals is too dense (on surface glass is dense too, but it has an actual surface, which is glass and then suddenly air, which can't stop glass moving outwards). That wave travels around ball and when it reaches opposite side - it amplificated, because waves combine at a single spot at same time and pushes glass outwards. This rips glass into pieces. And more it shatters in front - less it will shatter on back, because that glass powder absorbs a tons of kinetic energy. If not for that big latitudal crack from 5.56, you'd probably see a pretty big hole on back side. p.s. also, yeah, you theoretically could get silicosis, but for that you'd need to shoot and inhale glass particles for days, weeks or months.
The pressure wave can go thru the body as well. That's how you get spalling in tanks. The reason the crack is exactly opposite is thats where the reflection of the wave occurs. Mechanical spall happens at the reflection point.
One of the interesting facets of this experiment, was that all four initial calibers failed to push the ball off its stand. I would have thought there was much more energy transfer.
Depends on the weight of the ball and how the friction force keeps the ball in place, which each bullet likely doesn't carry enough momentum to be transfered to move it much and overcome the larger friction force
Perhaps an example of momentum versus kinetic energy. momentum = m * v, energy = 1/2 m * v^2. So, I'd say a much heavier and slower projectile, at the same energy, would have a chance to knock it over.
@@panman1964 Why not both? Actually, Slomo Guys borrow Destin's cameras all the time so if Matt collabs with Destin, we could get all desires satisfied.
It’s reverberation waves traveling through the glass and then impinging on an almost single point to fracture the glass. It happens in the opposite side because that is where all of the waves collide together and have enough energy to damage the surface. It’s neat stuff.
And remember kids: Inhaling glass dust is still deadly. There is a reason glassmaker have to wear masks or even respirators. Edit: Sorry DemolitionRanch if we in the comment section got your video demonetized again, but we gotta say something... I hope you are doing fine and A okay again^^
Yeah I was worried about this. When training on auto extrication for fire department we were taught to be very careful of this kind of glass dust, even in much lower quantities and less kinetic. I don’t know if there’s much they can do now Matt but I’d go see the doctor. Glass in your lungs is bad, and is likely the reason you’re indicating you can’t breathe well at the end of the vid.
Do not fear the bitter man, his anger is for sure. But even demons know to run when a kind one goes to war. Especially if he's Matt, because that fucker has more guns than some armies.
the impressive thing about glass is how hard it is. They even use stuff like glass to reinforce tank armour because of its crystalline structure it deflects energy really well the only problem being that it has relatively little tensile strength (it doesn't stretch very well) so while stuff like steel makes a good middle ground where it is very hard and stretchy enough that it doesn't just shatter under impact Glass is a lot harder so it makes a good element to composite materials. For instance lots of polymer frames for guns use powdered glass as a composite material to help strengthen the material
When you shoot it, the shock travels over the entire surface at the same speed (as shockwaves). This means that it all comes together at one point and creates enough kinetic force to make visible damage :)
Or it could be the same mechanism that causes spalling on armor, the impact sends a shockwave trough the volume of the material and on the other side a chunk of material is unsuppoorted and thus tears off since it has no other way of dealing with the energy.
You would think being a vet he would have had a least a little more insight into why he was sneezing. I mean after the .50 cal he even put his shirt over his nose for a second, like yeah dude, you should be wearing a mask.
Really disappointing that with all the money he makes he doesn’t raise the production value with stuff like that. Fpsrussia had a high speed like 8 years ago and RUclips is so much more competitive now
You're breathing in glass particulates every time you walk towards it. It's pulverizing some of the glass - so fine, that its lingering in the air after like dust. The fact that you sneezed everytime confirms that. You should have definitely worn a mask and eye protection. That stuff causes long term damage when inhaled.
The long term damage is from crystalline silica, not amorphous, which is what Matt is inhaling. crystalline silica is what glass is created with which is why they wear masks in that context. Obviously breathing in anything other than clean air isn't fantastic for you, but it's nowhere near as harmful as people are making it out to be
As others have said, this is perfect for a SmarterEveryDay collab! Destin has the phantom camera, likes guns, and understands physics enough to explain things. Please make this happen 🙏🏻🙌🏻
Because it is a perfect sphere, the energy is equally distributed throughout the entire cross sectional area until the energy converges at a single point on the posterior side of the sphere, causing more damage
@@21shoebills39 Imagine throwing a rock in a pond and watching the ripples go out. Now imagine the pond was a sphere. The ripples would all come together on the backside of the sphere and kind of act like the initial rock.
The cracks on the back are called "spalling." It's created from the Shockwave moving through a solid object and fracturing the other side. It's how certain types of anti armor tank rounds work. It is Also the reason why you need soft armor behind hard armor.
The type of shell that causes spalling is HESH (high explosive squash head). It is filled with plastic explosive and it pancakes out on the armour and transfers the force through the armour, shooting rivets and other small objects around the compartment acting as shrapnel. HESH is mostly used by the British
Engineer's explanation (could be wrong, tell me your hypothesis): The impact of the bullet causes a mechanical wave through the ball. It bounces of the sides of the ball and travels further through the ball. Because of the ball shape, when the waves meet at the opposite side of the impact, they constructively interfere to deliver a big impact of kinetic energy on that side as well. And it probably then cracked at some imperfection in the glass ball.
I agree, and the deformation caused by the wave is a lot more likely to make surface areas shatter, because they are where it's not just concentrated glass, what contracts and expands at more glass. (maybe, perhaps.)
Glass is fluid, despite seeming very 'solid-like'. So the reason you get a crack at the other end is because there is actually a ripple effect, like if you drop a pebble in water. The ripple runs evenly through the glass ball and meets at the centre at the opposite end. Then the same thing happens as when two waves meet in water, the glass waves amplify causing the glass to crack. (Not an engineer, so this is just my guess)
Glass is a super cooled liquid not a solid so as other people have pointed out the kinetic energy of the projectile travels as a wave through the glass. When the wave reaches the outer part on the opposite side it then damages the glass on the reverse of the ball

Yeah he should get chceked out. And if he does this again next time, get like a mask. Not like a anti-covid mask, but like an anti-fiberglass mask or asbestos.
We can call that wav of energy the impact force. Although the bullet doesn't penetrate, its impact force continues through. This really shows you a guns stopping power.
you’ll see this in planetary dynamics too. large impact sites on moons will have an associated region on the other side where there is fissuring from the waves coalescing.
We need to get SmarterEveryDay to do some slo mo on this. He would probably be able to figure out the “impact” on the opposite side too. We need a collaboration!!
I believe it’s acting like Newton’s Cradle. The impact goes through the class untouched like the middle balls and the backside cracks like the last ball.
Newtons cradle is more of energy transfer from on object to another. This is more of energy waves traveling through a medium. Imagine a stone thrown into a perfectly circular lake and the water ripples bouncing off the side and converging back in the center.
Whats happening is the force from the bullet it traveling in a strait formation rather than spreading throughout the ball thus causing the little cracks at the back.
The "allergies" could be micro glass resulting from high impact damage. You might wanna use a resp etc for future projects like this. Glass insulation is terrible for, and known for the same effects when anyone works with it and its is worse when you have to cut it, stuff it, or manipulate it in any way.
100% i used to have a glass blowing studio in my garage. i felt bad watching this. those micro shards are prolly gonna be logged in his nasal cavity and lungs forever lol....idk how bad it really is, but i can't imagine it's good lol
At what point does glass turn back into sand? Are we talking artillery shell concussion to remake the glass sand beaches? Or just a minor C4 explosion?
Ok, here's what happens inside the glass: The shockwave travels through the inside of the glass, gets reflected off the surface and the reflected shockwaves meet for positive interference at the exact opposite point of impact. There the stress on the material is so great that its structural integrity is compromised. While the single shockwave doesn't do anything to the structural integrity, the point where all the shockwaves meet is where the glass gets ripped apart. Like in the ocean where freak waves appear. Same principle. Positive interference. Shockwaves overlay each other to become a monster shockwave at that point.
@@odynzeyez6259 Technically it's not really kinetic energy in the form of what a 4th grader thinks it is, as it's more akin to sound. But as there is no real difference, you can say it's kinetic energy. Keep in mind though, that also thermal energy is kinetic energy in a weird way, so I'd rather stay quite precise than to be vague in order to keep it as scientifically sound as possible without making it only understandable for a physics phd. It's a fine line for complex subjects like this.
@@IIIAnchani So based on what your saying, he probably could have gotten more of this effect with a bigger slower bullet? I'd love to see a part II to this video with a high speed camera.
Yeah, that's actually really unsafe. He really needs to be wearing a respirator. Fine glass particles/glass dust-otherwise known as crystalline silica is extremely dangerous to humans. It can get into your lungs and cause all sorts of nasty problems, including lung cancer.
Geologist throwing an idea in. Historically, when Earth would be hit by a major bolide impact, a ripple would travel across the surface and cause an eruption of magma on the other side of the Earth. Can't give the deeper physics behind it but the surface momentarily acts almost like a liquid and allows a wave to propagate across the surface, all coming together on the back, and with nowhere to go it just kinda implodes at the opposite side of the sphere.
Yup same concept, the energy is transferred super well around and through the glass but since it's a sphere it all converges on one point in the back where it cracks
This was my thought process too. The structural integrity of a sphere, like the 2D concept of a curved arch, is what makes them so strong; being that the kinetic load would travel around the surface of the curvature like tsunami waves and colliding on the back side. We need #SmarterEveryDay to look into this now.
When the bullet hits, all the kinetic energy is expended into the surface which is why there are ripples on the shoot zone. The waves travel around the glass and they stop and the end and the energy tried to escape from the back going around the glass. That’s my best guess.
Close but not exactly. The hit started as a small circle wave where the bullet hit, then went through the surface of the sphere becoming larger and larger (so the energy was less focused), then it moved past the half of the ball (where it was the least focused because it was spread over the biggest area), and started going smaller and smaller again, and then it focused into a point on the exact opposite side of the ball and it again became strong enough to break glass. So it's not that it "couldn't escape", it's all about energy/area.
He has the money to buy a ultra slow motion camera but the issue is not just buying a camera but buying a PC that can process and hold all of the recording space needed for it. Slow mo guys had to have a 7k$ computer built just to hold enough for a year's worth of footage.
I just REALLY hope he is okay, there are actually micro particles of glass in his lungs that could tear them apart from the inside before his body rounds their edges. Unlikely given the size though, he is lucky it wasn't diamond or crystal.
Look into “Price Ruperts Drop” There are slow motion videos of shooting this glass tear drop that completely absorbs the energy without breaking, transfers the energy to the tail of the glass drop, THEN shatters from the tail back forward to the front (bulb) end of the tear drop.
8:03 I think it’s the same physics that HESH shells take advantage of. A compressive shockwave from the impact of the round is being propagated through the glass from the point of impact. When it hits the other side, part of the shockwave is internally reflected as a tension wave. The intersection of the wavefronts of the tension and compression waves causes a high stress zone which could lead to spalling. I suspect that the curvature of the sphere causing the tension waves to be focused on a specific region in the sphere is what is causing the unique effect.
@@CF-qm1gp If you consider the size of the ball in relation to the speed of the bullet the asteroid would have to be extremely fast to have the same impact on earth. And on top of that the earth is not like a solid glass ball it would probably behave differently. But I guess we will only find out when we all die... or if someone would just calculate it.
For simplicity: Just imagine your shot is like throwing a stone into a body of water. Waves ripple from the point of impact. Now your body of water is glass and round. A big part of the force is traveling in every direction around the glass ball in a wave form. On the other side the waves all merge together, bringing all that energy and having nowhere to go they make the force travel inside and outside. It should be the same vector as the bullet if we can assume that the traveling speed is the same throughout and on top of the glass So, to some degree it directs the force to the inside and the other part travels on the outside and meets on the back. If you have ever seen waves crashing together, this is what happens with an infinite number of tiny waves
@@simeonhoppmann4091 NO! The scientific explanation is that the ball was at 100 shield and 100 health. Assuming the pistols he used were rare rarity, it would do 26 damage. It would take 4 bullets to crack its shield, and another 4 to finally elimate it. The smaller ball was cracked and had 100 health.
@@rasmus5079 ruclips.net/video/Wp6bN9vN6e4/видео.html this is the best i can supply as an explanation with the only addition being glass is seen as a liquid from a physics standpoint so fluid dynamics plays a role here otherwise imagine it as if you shot a 30 foot sphere of ice with a 50 cal damage would be similar to the 45 acp on the big glass ball assuming you could get a pristine flawless 30 foot sphere of ice or we could trap a sphere of water of the same size in a zone of super slow time
The part that breaks on the other side is called "spalling" same thing happens to old style tank armor when it was over hardened. The energy of a shot doesn't pierce through but causes shards to shoot off on the other side of the point of impact, often wounding the crew.
I believe the word you're looking for is "spalling." You see, the reason that the British favoured High Explosive Squash Head (HESH) rounds for their main battle tanks during the cold war was because a HESH round does NOT need to penetrate the armour of an enemy tank to be lethal/ effective. Instead, this spalling effect launches fragments of metal from the armour of the tank, through the interior, killing the crew without ever actually penetrating the armour. Rather than try to explain how this works myself, I've simply copy-n-pasted a paragraph from the Wikipedia entry on HESH rounds. It explains the mechanisms at work that result in spalling: HESH rounds are thin metal shells filled with plastic explosive and a delayed-action base fuze. The plastic explosive is "squashed" against the surface of the target on impact and spreads out to form a disc or "pat" of explosive. The base fuze detonates the explosive milliseconds later, creating a shock wave that, owing to its large surface area and direct contact with the target, is transmitted through the material. In the case of the metal armour of a tank, the compression shock wave is conducted through the armour to the point where it reaches the metal/air interface (the hollow crew compartment), where some of the energy is reflected as a tension wave. At the point where the compression and tension waves intersect, a high-stress zone is created in the metal, causing pieces of steel to be projected off the interior wall at high velocity. This fragmentation by blast wave is known as spalling, with the fragments themselves known as spall. The spall travels through the interior of the vehicle at high velocity, killing or injuring the crew, damaging equipment, and/or igniting ammunition and fuel. Unlike high-explosive anti-tank (HEAT) rounds, which are shaped charge ammunition, HESH shells are not specifically designed to perforate the armour of main battle tanks. HESH shells rely instead on the transmission of the shock wave through the solid steel armour.
You gotta get Destin on this. Do a collab with Smarter Every Day. He'll figure it out.

The damage on the back is called "spalling". It's when the pressure waves inside the material reach the back surface, and create stresses in the material large enough to fracture. It's one of the reason armor plates have to be spall coated. There are also some anti armor weapons that use spallation to create shrapnel on the inside of an armored vehicle or structure without penetrating. The shockwave just blasts shrapnel off the backside when it propagates thorough.

This.
This, but with the emphasis on how simple & obvious it is.
Yeah along with that glass behaves a lot like a liquid in those aspects aswell.
I believe the scientific term is a Coney joney
For every action there is an equal and opposite reaction
It's sending energy around the edges all the way around by miniscule amounts of movement in the glass caused by the high speed of the bullet, all of that force collides with itself on the farther point from the point of impact, that being said, when you switched to the second ball and used the higher velocity shots, the force was enough to extend off the sides rather than follow around the curve. (That's why it had the large round cracks halfway through)
The same thing happened on Mercury and the Caloris Basin, on the opposite side of the planet there is an odd area filled with random jumbled hills
@@MarcusPerkinsJr-n8u Damn, I wish I could see a video of that happening!
In a nutshell, what is happening is that the force transfers around and through the ball, until the different waves meet at the point exactly opposite the initial impact, adding themselves back together, thus making a force with both nowhere to go, and one that is too strong for the glass to hold. A really cool and interesting phenomenon.
Like the Dim Mak in Bloodsport
Thank you. I'm suprised he didn't figure it out himself.

NEEEEEEEEEEERRDDD
The reason that the back is cracked is based on the shape of the sphere and how it distributes force. Arches (and spheres) apply force throughout the entire surface. The cracks are formed when the forces travel around the surface of the sphere and collide.
Also, when enough force is applied to armor to cause the back to break off, it's called spalling. Not sure if it applies here though.
I was thinking the same thing
The British developed HESH (High Explosive Squash Head) ammunition that plastered a large amount of plastic explosive to armor plate and then detonated it with the rear of the shell after it had squashed as opposed to using the front to detonate on contact like standard HE rounds. This send a shockwave directly through the material causing it to spall on the inside when the shockwave reached the back side of the armor. With no further armor there to support it the force of the shockwave exceeds the strength of the material causing it to fail. This is likely what is occurring here rather than the shock wave traveling around the outside as the shock wave from the impact would arrive at the back much more quickly traveling directly through the center rather than around the outside much like seismic waves through the earth. In addition the other shot locations would cause the shock traveling around the outside to cause additional damage at those locations as they are flaws in the shape much like how a tin can can hold a heavy load in the axial direction until you introduce a small flaw and it collapses violently and suddenly.
Smart
I dont under stand but smart
Thats exactly what I was coming to comment, thanks man
@@bloodandoil9226 It only happened with the slower pistol rounds which had wider and blunter tips compared to the faster moving rifle rounds. Was able to transfer the force of the bullet through the glass instead of penetrating it.
"What is happening?"
When a pebble drops into a pond, it sends out ripples, yes? On a sphere, those ripples extend outwards, across the sphere, and converge at a single point directly opposite the point of impact, creating a disturbance comparable to the original impact. This forms the crack on the back side.
Probably more like a newton's cradle
@@Mikhail-Tkachenko similar yes. It’s called energy transference. The same thing happens when a meteor collided with the surface of a planet.
Wait, so cintrivical force??? Or something different
From an impact like that (or any impact really), the molecules of the glass ball REALLY want to move and react, but can't due to their structure. The shockwave from the bullet can't dramatically affect the structure of the interior because the interior is simply too tough. The area that CAN be affected is the area with the weakest defense from the shockwave as it passes through: the narrowing opposite side. Think of the force like a diamond: the sharp end (the shockwave of the impact) is lessened by the interior (the thick middle) and exits the opposite side (the opposite sharp end). I think it may even be more than that, though. Waves echo through materials, through air or through solids. The shockwave might have "bounced" from the impact, to the opposite end, and back again. Right at that area of "echo", you have an area of reflection that might have created the crack. I'm thinking it's something like this in the case of the massive .44 magnum.
You explained it far better than I was going to, but yep....Right answer here^^
What else is amazing is how the ball absorbs the energy, and doesn't knock it out of the stand.
Kinetic lensing. The shock wave "ripples" to a focal point on the back.
I like that he didn’t think anything of the ripples left behind, I wish he put a slo mo camera up in the back so we could watch it all meet and explode the back out.

Lol😝😝😝😝😝😝
Yep
if you have it sighted in for pretty long range(nothing past where the bullet is dropping), it will generally hit around as low as the distance from the center of your scope down to the center of your barrel when shot at close range.

I like the way the camera pans back and forth at the beginning, and it’s a pretty smooth transition too
One of the best “intros”
The “counter impact” is known as spalling. The force from the bullet impacting transfers to the opposite face of the glass ball and causes it to split off or “spall”. This occurs with harder objects such as tank armor and there are specific types of ordnance known as HEP rounds that don’t penetrate armor but cause it to spall on the inside surface tearing up the inside of the tank or armored vehicle.

The glass acts this way for the same reason a newton's cradle only effects the opposite ball. The energy travels through and is released through the last bit of material. This could be better explained but iam not an educator.
It releases as it’s about to lose all energy
*not tryna correct you. Everything else is correct except it’s not exactly like the cradle*
@@joshb2492 Newtons cradle is a physical example of conservation of momentum and the conservation of energy. It's exactly like that
Good enough for me good answer👍
Any of the excess energy from the initial impact that wasn't released through sound heat and the cracks in the ball traveled through until it hit the back and came together for a second impact
So it did show conservation of energy
Answer for why there is a crack on the other side:
This is the forensic scientists' [3R] rule-radial cracks make right angles to the rear. In a concentric crack, it's the opposite-the chonchoidal fractures DO make a right angle to the side the force came from. This can be vitally important in determining if something was a shoot-out or a shoot-in.

Next time on Demolition Ranch: Can COVID stop a .50 cal?
Explanation on the little crack: When the bullet hits, it send out vibrations in all directions, and the crack is resulting from the vibrations all meeting back up on the other side. The crack should be almost exactly opposite of the initial impact.
Yepp, same with earthquakes and how we measure them. Also, thats how some major volcanoe provinces in earths history are supposed to happen at the backside of earth when an asteroid hit.
Planet Mars has volcanoes on opposite side of planet where big meteor hit...same phenomenon here
I was going to say the same thing, but didn't want to be that repeat guy. I love physics, didn't take long with a little ponder. but the physics is a little more complex than that. notice the small crack is always somewhere inside the ball. the vibrations do indeed travel in all directions, even across the surface, but the vibrations continue multiple passes around the ball before all meet together. the surface vibrations have a longer time traveling to opposite side as direct line will be shorter. therefore, the vibrations direct line head back towards the front again before surface reaches the back. my guess these vibrations bounce around a bit off of one another till enough vibrations meet together to expend energy in the breaking of the glass somewhere inside

@@christienewton1048 rather know the fact and be a nerd rather than not and be smartass
That intro is just amazing! Look at all the transitions between characters, that's some real level of filming, ngl
the effect is called spalling. it happens when energy travels through an object and breaks pieces off the other side of the object. it's the principle behind HESH projectiles.
That is why military vehicles have a spall liner. It's Kevlar lining to stop spalling fragments from injuring soldiers.

Well at least your close. The sphere actually focuses the shockwave to a point on the other side. When spalling happens in armor it's in a wider area. Same thing though lol
@@davidfreeman1774 Yea, I kind of thought he was joking when he said he didn't know.
Kinda reminds me of how JFK was killed from within the car.
The momentum of the bullet is carried trough the glass and comes together at the opposite end which creates a more concentrated spot of energy which makes the glass crack
😦
No the bullet has a hidden tiny bullet that it shoots when it hits the intended target.
Please be scientific, you sound like an 8 year old
I'm glad someone said this.
Its called a Hertzian cone and isn't really like you explained it dude
The first 2 minutes was the best editing I've seen!
its called a conical fracture, when a spherical object made of a non-flexible material (glass, ice ,ect) is impacted it fractures in this way because the force of the impact is distributed outwards creating the cone shape and the secondary concussion creates the smaller chip/crack at the back
Also, glass is an amorphous solid so it doesn't break apart like metal or rock would. Reaction forces from amorphous solids are much different than crystalline.
You two together make up the iq of the rest of the comments here XD
@@LangsamUndLaut Knowledge --> high iq? And does iq even reflect intelligence well and in what areas?
In less smart words so regular people can understand,
Basically the force of the bullet vibrates through the glass and when it is at the end of the sphere it pushes off into the open air wich cracks the back of the sphere.
So the force moves around the ball until it collides together on the back cracking it?¿
Matt: *Stands in a cloud of vaporized glass*

The day he got lung cancer
@@sethhorras8519 ajjajajjajajajjajajja
*inhales deeply*
Not vaporized, powdered glass.
That's vibrations what crack the ball at the other side. Essentially, when bullet hits, it creates a pressure wave, mostly on surface, because only surface can actually transmit wave, as internals is too dense (on surface glass is dense too, but it has an actual surface, which is glass and then suddenly air, which can't stop glass moving outwards). That wave travels around ball and when it reaches opposite side - it amplificated, because waves combine at a single spot at same time and pushes glass outwards. This rips glass into pieces.
And more it shatters in front - less it will shatter on back, because that glass powder absorbs a tons of kinetic energy. If not for that big latitudal crack from 5.56, you'd probably see a pretty big hole on back side.
p.s. also, yeah, you theoretically could get silicosis, but for that you'd need to shoot and inhale glass particles for days, weeks or months.
So Basically think of newton's cradle
The pressure wave can go thru the body as well. That's how you get spalling in tanks.
The reason the crack is exactly opposite is thats where the reflection of the wave occurs.
Mechanical spall happens at the reflection point.
It's kinda like how HESH shells work
@@Zachavius exactly
@@0dustyn066 exactly what I was thinking
One of the interesting facets of this experiment, was that all four initial calibers failed to push the ball off its stand. I would have thought there was much more energy transfer.
Depends on the weight of the ball and how the friction force keeps the ball in place, which each bullet likely doesn't carry enough momentum to be transfered to move it much and overcome the larger friction force
Perhaps an example of momentum versus kinetic energy. momentum = m * v, energy = 1/2 m * v^2. So, I'd say a much heavier and slower projectile, at the same energy, would have a chance to knock it over.
a collab with Destin Sandlin "Smarter Every Day" would explain this tear on the back side . i would love to see it
I'd settle for some HQ slo mo :)
@@panman1964 Why not both? Actually, Slomo Guys borrow Destin's cameras all the time so if Matt collabs with Destin, we could get all desires satisfied.
I second that motion
Look up conical fracture
It’s reverberation waves traveling through the glass and then impinging on an almost single point to fracture the glass. It happens in the opposite side because that is where all of the waves collide together and have enough energy to damage the surface. It’s neat stuff.
It would be neat to see this in very slow motion. At a high enough frame rate you could probably see the wave moving across the surface.

👌 isn't he a veterinarian? You would think he would know better 😆
the impressive thing about glass is how hard it is. They even use stuff like glass to reinforce tank armour because of its crystalline structure it deflects energy really well the only problem being that it has relatively little tensile strength (it doesn't stretch very well) so while stuff like steel makes a good middle ground where it is very hard and stretchy enough that it doesn't just shatter under impact Glass is a lot harder so it makes a good element to composite materials. For instance lots of polymer frames for guns use powdered glass as a composite material to help strengthen the material
When you shoot it, the shock travels over the entire surface at the same speed (as shockwaves). This means that it all comes together at one point and creates enough kinetic force to make visible damage :)
It took a while to find this comment because of all the "i'm not allergic" comments
Dem shk fr🤣
Well said. Where are you from ?
Or it could be the same mechanism that causes spalling on armor, the impact sends a shockwave trough the volume of the material and on the other side a chunk of material is unsuppoorted and thus tears off since it has no other way of dealing with the energy.
Faster than normal shockwaves, same as how sound travels through glas (way more quickly)

You're breathing in glass particulates every time you walk towards it. It's pulverizing some of the glass - so fine, that its lingering in the air after like dust. The fact that you sneezed everytime confirms that. You should have definitely worn a mask and eye protection. That stuff causes long term damage when inhaled.
The long term damage is from crystalline silica, not amorphous, which is what Matt is inhaling. crystalline silica is what glass is created with which is why they wear masks in that context. Obviously breathing in anything other than clean air isn't fantastic for you, but it's nowhere near as harmful as people are making it out to be

U r big brain
The cracks on the back are called "spalling." It's created from the Shockwave moving through a solid object and fracturing the other side. It's how certain types of anti armor tank rounds work. It is Also the reason why you need soft armor behind hard armor.
God, can you imagine the first tank crews that found out the hard way what spalling was? Messy!
Nah, it's a coney-joney
The type of shell that causes spalling is HESH (high explosive squash head). It is filled with plastic explosive and it pancakes out on the armour and transfers the force through the armour, shooting rivets and other small objects around the compartment acting as shrapnel. HESH is mostly used by the British
@@CheeseDanish85 Rifle fire would do it to the first tanks, the crews wore chain mail masks to protect them.
Glad someone else knew this, I actually thought it was pretty common knowledge among gun nuts
That beginning skit was amazing
Engineer's explanation (could be wrong, tell me your hypothesis): The impact of the bullet causes a mechanical wave through the ball. It bounces of the sides of the ball and travels further through the ball. Because of the ball shape, when the waves meet at the opposite side of the impact, they constructively interfere to deliver a big impact of kinetic energy on that side as well. And it probably then cracked at some imperfection in the glass ball.
I agree, and the deformation caused by the wave is a lot more likely to make surface areas shatter, because they are where it's not just concentrated glass, what contracts and expands at more glass. (maybe, perhaps.)
I kind of have a hard time expressing what i mean without sketches, hope you get the gist of what i mean, anyways.
Glass is fluid, despite seeming very 'solid-like'. So the reason you get a crack at the other end is because there is actually a ripple effect, like if you drop a pebble in water. The ripple runs evenly through the glass ball and meets at the centre at the opposite end. Then the same thing happens as when two waves meet in water, the glass waves amplify causing the glass to crack.
(Not an engineer, so this is just my guess)
Glass is a super cooled liquid not a solid so as other people have pointed out the kinetic energy of the projectile travels as a wave through the glass. When the wave reaches the outer part on the opposite side it then damages the glass on the reverse of the ball
Yeah it's kinda how HESH ammunition works. Just google it and you get the idea.

I believe it’s acting like Newton’s Cradle. The impact goes through the class untouched like the middle balls and the backside cracks like the last ball.
I think it's the concussion wave meeting at that point. It ripples around the ball then collides at that single point? That's my guess
Newtons cradle is more of energy transfer from on object to another. This is more of energy waves traveling through a medium. Imagine a stone thrown into a perfectly circular lake and the water ripples bouncing off the side and converging back in the center.
I made a more detailed explanation
Whats happening is the force from the bullet it traveling in a strait formation rather than spreading throughout the ball thus causing the little cracks at the back.

Ok, here's what happens inside the glass:
The shockwave travels through the inside of the glass, gets reflected off the surface and the reflected shockwaves meet for positive interference at the exact opposite point of impact. There the stress on the material is so great that its structural integrity is compromised. While the single shockwave doesn't do anything to the structural integrity, the point where all the shockwaves meet is where the glass gets ripped apart. Like in the ocean where freak waves appear. Same principle. Positive interference. Shockwaves overlay each other to become a monster shockwave at that point.

@@odynzeyez6259 Technically it's not really kinetic energy in the form of what a 4th grader thinks it is, as it's more akin to sound.

Geologist throwing an idea in. Historically, when Earth would be hit by a major bolide impact, a ripple would travel across the surface and cause an eruption of magma on the other side of the Earth. Can't give the deeper physics behind it but the surface momentarily acts almost like a liquid and allows a wave to propagate across the surface, all coming together on the back, and with nowhere to go it just kinda implodes at the opposite side of the sphere.
Yup same concept, the energy is transferred super well around and through the glass but since it's a sphere it all converges on one point in the back where it cracks
physicist here, can confirm
This is science.
This was my thought process too. The structural integrity of a sphere, like the 2D concept of a curved arch, is what makes them so strong; being that the kinetic load would travel around the surface of the curvature like tsunami waves and colliding on the back side. We need #SmarterEveryDay to look into this now.
Now I have something smart to say in earth science. Thanks!
This man got some of the most hilarious skits, dude don't even need an intro the skits are enough 😂
When the bullet hits, all the kinetic energy is expended into the surface which is why there are ripples on the shoot zone. The waves travel around the glass and they stop and the end and the energy tried to escape from the back going around the glass. That’s my best guess.
Thank you I just thought everyone here was stupid
But I see you are educated
The samething happens with HESH rounds against armor.
Close but not exactly. The hit started as a small circle wave where the bullet hit, then went through the surface of the sphere becoming larger and larger (so the energy was less focused), then it moved past the half of the ball (where it was the least focused because it was spread over the biggest area), and started going smaller and smaller again, and then it focused into a point on the exact opposite side of the ball and it again became strong enough to break glass. So it's not that it "couldn't escape", it's all about energy/area.
@@ajuc005 indeed the cracks on the subsequent side are a sign of the kinetic energy escaping the sphere via kinetic wave. Quite entertaining.

He has the money to buy a ultra slow motion camera but the issue is not just buying a camera but buying a PC that can process and hold all of the recording space needed for it. Slow mo guys had to have a 7k$ computer built just to hold enough for a year's worth of footage.

he's not wrong. having glass lung is like being cursed.
I just REALLY hope he is okay, there are actually micro particles of glass in his lungs that could tear them apart from the inside before his body rounds their edges. Unlikely given the size though, he is lucky it wasn't diamond or crystal.
@@gonorsilvet2581 I don’t think he would shoot at a solid ball of diamond

That “exit” crack needs to be recorded in slo mo, mando
Look into “Price Ruperts Drop”
There are slow motion videos of shooting this glass tear drop that completely absorbs the energy without breaking, transfers the energy to the tail of the glass drop, THEN shatters from the tail back forward to the front (bulb) end of the tear drop.

8:03 I think it’s the same physics that HESH shells take advantage of. A compressive shockwave from the impact of the round is being propagated through the glass from the point of impact. When it hits the other side, part of the shockwave is internally reflected as a tension wave. The intersection of the wavefronts of the tension and compression waves causes a high stress zone which could lead to spalling. I suspect that the curvature of the sphere causing the tension waves to be focused on a specific region in the sphere is what is causing the unique effect.
so if an asteroid hit earth would it be like we got hit by a hesh round
@@CF-qm1gp If you consider the size of the ball in relation to the speed of the bullet the asteroid would have to be extremely fast to have the same impact on earth. And on top of that the earth is not like a solid glass ball it would probably behave differently. But I guess we will only find out when we all die... or if someone would just calculate it.
It's also due to a sphere that size forming layers as it cools.
yea when he asked that question i immediately was like "it spalled lmao"
@@dr_duck___3529 hopefully when we all die someone in the ISS will be recording it at 3,000 FPS so he can submit it to youtube
For simplicity: Just imagine your shot is like throwing a stone into a body of water. Waves ripple from the point of impact. Now your body of water is glass and round. A big part of the force is traveling in every direction around the glass ball in a wave form. On the other side the waves all merge together, bringing all that energy and having nowhere to go they make the force travel inside and outside. It should be the same vector as the bullet if we can assume that the traveling speed is the same throughout and on top of the glass
So, to some degree it directs the force to the inside and the other part travels on the outside and meets on the back.
If you have ever seen waves crashing together, this is what happens with an infinite number of tiny waves
That was a nice explanation thanks
What about without the simplicity?
@@simeonhoppmann4091 NO! The scientific explanation is that the ball was at 100 shield and 100 health. Assuming the pistols he used were rare rarity, it would do 26 damage. It would take 4 bullets to crack its shield, and another 4 to finally elimate it. The smaller ball was cracked and had 100 health.
@@rasmus5079 ruclips.net/video/Wp6bN9vN6e4/видео.html this is the best i can supply as an explanation with the only addition being glass is seen as a liquid from a physics standpoint so fluid dynamics plays a role here otherwise imagine it as if you shot a 30 foot sphere of ice with a 50 cal damage would be similar to the 45 acp on the big glass ball assuming you could get a pristine flawless 30 foot sphere of ice or we could trap a sphere of water of the same size in a zone of super slow time
I needed that
The part that breaks on the other side is called "spalling" same thing happens to old style tank armor when it was over hardened. The energy of a shot doesn't pierce through but causes shards to shoot off on the other side of the point of impact, often wounding the crew.
I believe the word you're looking for is "spalling."
You see, the reason that the British favoured High Explosive Squash Head (HESH) rounds for their main battle tanks during the cold war was because a HESH round does NOT need to penetrate the armour of an enemy tank to be lethal/ effective. Instead, this spalling effect launches fragments of metal from the armour of the tank, through the interior, killing the crew without ever actually penetrating the armour. Rather than try to explain how this works myself, I've simply copy-n-pasted a paragraph from the Wikipedia entry on HESH rounds. It explains the mechanisms at work that result in spalling:
HESH rounds are thin metal shells filled with plastic explosive and a delayed-action base fuze. The plastic explosive is "squashed" against the surface of the target on impact and spreads out to form a disc or "pat" of explosive. The base fuze detonates the explosive milliseconds later, creating a shock wave that, owing to its large surface area and direct contact with the target, is transmitted through the material. In the case of the metal armour of a tank, the compression shock wave is conducted through the armour to the point where it reaches the metal/air interface (the hollow crew compartment), where some of the energy is reflected as a tension wave. At the point where the compression and tension waves intersect, a high-stress zone is created in the metal, causing pieces of steel to be projected off the interior wall at high velocity. This fragmentation by blast wave is known as spalling, with the fragments themselves known as spall. The spall travels through the interior of the vehicle at high velocity, killing or injuring the crew, damaging equipment, and/or igniting ammunition and fuel. Unlike high-explosive anti-tank (HEAT) rounds, which are shaped charge ammunition, HESH shells are not specifically designed to perforate the armour of main battle tanks. HESH shells rely instead on the transmission of the shock wave through the solid steel armour.
ok mr science man
