The arrows turning into one purple one when they meet is a really nice touch.
It's the little things
Also notice how the radius of fractured glass starts from small and gets larger as it moves forward...

Wow that's a great name lol
Dan is probably a candidate for the "most glass smashed by a single person" record at this point
Well there is super humman, whose youtube channel is devoted to front flipping onto fluorescent light tubes and such for all the juggalos and juggalettes out there

The bullet travels in a straight line, but the glass splinters out cracking every inch as it goes on. Its like racing someone who's running literal circles around you, after having lapped you.
To be fair, it can go forwards and outwards at the same time, I think.
Nah, The cracks are not traveling. The shockwave is, and the cracks just follow.
Silver Blast; tripe.
I looked it up and apparently the fastest cartridge is the .220 Swift, which has a published speed of about 3181mph. So it’d be really close to the glass breaking. I’d be curious to see it
About the closest factory ballistics would be the 22-250 rem with 35gn projectiles (factory ballistics of 4250fps) the glass is approximately 4600fps in this video, there are wildcat rounds that are faster, gs custom in south Africa had one to 5200fps
Well if we'll go all out on guns I would think supcaliber rounds out of tank cannons cann be faster than the glass breaking
Since I recall same numbers form the Leo2A5 and following models the muzzle velocity of the APFSD round out of the rh120 l55 is about 1750m/s so the 9mm on top of the glass breaking soo yeah ther is probably a gun and round at about 1436m/s so the exact same speed
@@TheLtVoss Not to mention how cool it would be to see Dan fire the Rh120 L/55 - I'm sure they can borrow one of those for a vid.
That and shoot the glass.
Should shoot the glass with the bullet to get a real-time comparison
Dan’s firearm discipline is always a joy to see.
British Army training.
He's usually such a messy goofball, and then the guns or explosives come out and then he's absolute all business.
It's almost like proper vetting and training for gun owners makes everyone safer

Very proud of you guys for this one. Good job!
Are they trying to tell us the speed of sound is faster in glass than air?
I don't get it.. 😂
@@jonslg240
I don't remember why, but yes, the speed of sound is indeed faster through solid objects than through liquids or gases.
@@jonslg240 speed of sound changes depending on what the sound is traveling through.
For example, speed of sound is quite fast in metals, partially responsible for why metal stuff is so loud when you hit it
Well, not straight but they did get to it.
@@jonslg240it is
The gun safety etiquette Dan always has is great to see. Many could learn from that, as in learn to be doing the most basic thing you should do when handling firearms. So many shout safe before even checking the chamber is clear because it’s just an automatic thing they through out after each shot, with the assumption that it will always be safe no matter what.
A lot better then a certain actor/ producer and armorer.
@@gilliganallmighty3 I can't remember if they said, but I hope that studio armorer got fired
One small thing I love about the slow mo guys is they always let things play out, like the bullet traveling all the way to the other side, without cutting or fast forwarding, just giving the aweseome footage the respect it deserves :D
Absolutely!
I think they have like a 4 hour video of a glass measuring cup shattering
@@jacobkeyser8628 19 hours and 5 minutes more like 😂
I think the biggest thing we learned from this video is that even if what you're filming isn't anything new, it's still gonna be fun just watching your banter
Bri'ish banta as weww. Although they are more RP than scouse
I reckon these guys could film paint drying in slow motion and make it interesting.
@@f.cscootriders It's more interesting if you speed it up and put it under a microscope. ruclips.net/video/OW5wB8rJ8Zc/видео.html (60 Symbols)
The discussion about the speed of sound in a solid (like glass) wraps back around to Gav's old question about the speed of push in a lovely way.
I was definitely surprised by how much faster the glass was. That was cool.
3:30 Different speeds of sound. Mind blown
Slow-mo speed comparisons is a surprisingly interesting AND satisfying thing to watch. Think you guys stumbled onto a goldmine with this one.
Yeah the glass cracking part was amazing, wished they had a faster rifle bullet instead.
Next is a 223 cartridge.
I appreciate how they always leave in all of Dan’s firearm and pyrotechnics safety steps, calling out ‘safe’ etc. What a pro!
I love it too, one because it shows that they care to do it right, and two because it shows how to do it right!
Basically most people who uses firearms in a recording session does that...... I hope?
He did not pull back the slide the check the breach after he dropped the mag out before putting it on safety.... Watch any professional or experienced firearms user he will pull the slid back once or twice to make sure that the breach is empty before he/she safes the gun... Yes I know he only put 1 bullet in the mag and put it on safe but for the sake of 1.5sec physical check of the breach is just good safe procedure
@@nigelsmith7366 does it need to be slid back if its already slid back?
@@nigelsmith7366 watch it again. He looks to see where the casing went, looks into the open slide, and then calls safe.
When you eventually get the chance (hopefully not in Texas) you guys should film snowballs hitting glass and exploding in slow motion. I bet that would look amazing!
I endlessly love how endlessly amazed you two remain after all these slow mo years.
The stunt safety in me is so happy watching Dan fire a single readied round and still checking the chamber is clear before calling safe.
Not just stunt safety but general firearms safety
Common sense
You would be surprised...
Well he was in the military, and that habit stays. Much like the trigger finger habit with anything that has a trigger.
I've noticed that some of the most dangerous stuff that happens isn't people new to handling something dangerous, but the people have handled it so much that they think that safety rules are for the new people.
For a next video, could you use a spring loaded glass crusher in the middle of a great sheet of glass, to see the circular propagation of the material-wave? And in a following experiment two or even three "epicenters" on the same sheet of glass which get triggered at the same time. Would be interesting to see 2 or 3 circular waves meeting each other, when the conducting medium already fails.
That would indeed be quite amazing. I hope they see this comment
I second. Like their comment.
They would have to be extremely in sync to actually see multiple crushers
Not sure how that would appear on playback, as their field of view gets thinner as the camera speed gets faster. So you might not be able to see everything at fast speeds or you see everything but it happens to quickly to see anything interesting at slower speeds.
@@d4rk0v3 What?
There is so much under appreciated talent in these videos that has absolutely nothing to do with filming things at high frame rates 🤣🤣🤣
Interesting how shape of the wavefront in the glass goes from round to almost straight because it forms a circle around the initial cracking point at all times
ok
I wish I had the words to describe this from a mathematical perspective. Something about the angle that defines a given section length at a given radius?
@@Beschaulichkeit I think because the glass cracks in a circle from the point of damage. Imagine the initial break being the centre of this circle. As it then enlarges, the edge of this circle appears straight because the circumference is so large. A bit like saying the earth is flat, no it’s just large
@@Beschaulichkeit "curvature is inversely proportional to the radius" is the magic words
@@sergey1519 Thank you!
I always thought it'd be interesting to see slow-mo of metal being machined. There are some channels that run the 120 or 240fps but using one of those insane macro lenses to get right up to the cutter and see how the metal reacts seems like it'd be interesting.
Just wanted to second this. Yes please.

There are definitely some ammos that would come very close to keeping up with the glass breaking. For example, the 4,000 Feet per second (2,727 MPH) 35gr .223 ammo, or the 4,300 feet per second (2,931 MPH) .220 Swift ammo.
I was going to comment, my dad used to hand load custom 220 swift rounds that were absolute heaters that would probably come close to the same speed as the glass
I was also thinking they should use a rifle instead. That round would probably keep up with the breaking glass.
The 223 WSM would be close in factory loadings, or if you went wildcat there is the 22 eargesplitten loudenboomer which is the 378 Weatherby Magnum necked to 22.
Dan certainly gets confused, it is not an order of magnitude faster (at least with the most commonly used base of magnitude of 10) as it is around 4 times faster. Which is a lot, but still feels like in the realm of possibility. Him casually throwing that ball certainly is an order (or two) of magnitude slower than a bullet though. While numbers are hard to get a feel for, apparently the video comparison didn't do it for Dan either.
.220 Swift and .22-250 are both ludicrously fast with certain loads, .22-250 may even by slightly easier to find.
The production quality in your videos is top shelf. Highly informative, and highly entertaining!
The arrow turning purple is so satisfying! I also love the music of the glass after it's cracked.
I'd like to see a time lapse of Dan's lab coat over the years. It has been through alot 😆
Me too
A .220 Swift is the closest bullet with a speed comparable to the speed of sound in glass. Would be very interesting to see how close they are!
The fastest published .220 swift was 4,665 FPS through a hand load (from p.o. Ackleys reloading handbook) The glass breaking in this video is moving at 4713 FPS. So pretty close but the glass is still slightly faster
The only rounds I can think of are modern smooth bore cannons shooting apfsds at speeds of over 1500m/s some over 1700m/s beyond that you would need a rail gun to go faster
The only rifle round that could beat the glass I think would be something ludicrous like the .22 Eargesplitten Loudenboomer. Yes it's a real wildcat cartridge lmao
@@oskar8413
P.O. Ackley was a mad genius...
I don't know why, but I loved watching the slow motion of that glass. It clicked something in my mind watching it spread like that.
You could try Darts hitting a dart board wayyy to fast! That would look cool in (macro) slow motion as well :p
Omg yess
Good Idea!
I think macro is hard to do since you don't want to hit the camera .-.
@@raphaelschneider4722 just shoot near the board. Should be doable
Seeing the glass and the bullet moving at the same time is really interesting and nice to see, combined that with the speed the Flash has some competition
But the Flash runs faster than time!
220 Swift should have exactly the same speed as glass
Now do the same thing with a .408 Cheytac (3500 ft/s), .50bmg (4000ft/s) or the big daddy .220 swift (4665 ft/s)
@@UnlovedD2 this

This experiment is now my new found knowledge. I never thought that a shattering glass would actually be able to beat a bullet. After your explanation on the speed of sound in different mediums, I recalled my lessons in science class. The speed of sound changes depending on the mediums state of matter. The more compact atoms are the easier sound and vibration travels
The quality of this video is incredible. Thanks
I love how the glass stays in place for about as long as it takes the bullet to travel the full distance
gravity has his own speed wich is way slower than a bullet
That's clearly a fast forward at the end 😄
The .220 swift can reach speeds of upwards of 4000 ft/s. Or Mach 4. That's the closest you might find. I happen to own a 6.5 creedmoor rifle, it pushes 3020 ft/s. I think there are some rifle cartridges that will give glass a run for its money!
Love the videos guys! Would love to see this revisited!
it would have to be a pretty hot .220 swift load, the glass is shattering at 4714 fps. I think the fastest factory load I've seen for .220 was 4600 or something
There would be wildcat calibers that would be faster I'd imagine, but yeah I suspect the glass would beat everything commercially available.
@@Mrx1080 Put the ol .17/50 incinerator in the lineup
From what I've read, there seems to be a practical "wall" at around 4600 feet/second. You can push it faster but accuracy is very poor, the bullets often break up, and barrels only last a few shots. .220 Swift is the fastest round in large-scale production as far as I know, and it is only about 300 fps slower than this "wall" which was achieved with the stupidly silly ".22 Eargesplitten Loudenboomer "
Is that muzzle velocity or downrange?
The glass isn't traveling at the speed of sound (3:36 reference). The glass is actually splitting apart faster than the speed of sound! Cool to see it together with the bullet like this!
the speed of sound depends on the medium it travels through. it's basically just how fast waves travel (we usually refer to speed of sound as this speed in air, as it is how we hear) the cracking of the glass is exactly that: a wave traveling through the glass. it's by definition the speed of sound in glass. harder glass will crack faster, because it has a higher speed of sound
You guys are the real gem of youtube, the real gem of youtube.
Just wanted to include the mind-blowing fact that in the first shot, the bullet is going at 343 m/s or 768mph, which is the EXACT speed of sound at 20°C! What a phenomenal coincidence and representation of the speed of sound!
I wondered this and googled the speed of sound and then checked back at the bullet speed 😮
Google says to expect "between 990 and 1350 feet per second." With the speed of sound being 1125 fps (343 m/s). That makes it reasonable median. So, I'm not shocked, except that it came out pretty close to _exact._
Given the time this was shot, it's probably exactly that temperature outside.
it would've slowed down a bit by the end of the 6ft
What does that mean? No sound?
“I do have some bushy wings on me.”
What an amazing Dan quote.
The way Gav completely lost his train of thought looking at him had me rolling 😂
I’ve been spinning coins a lot recently and no matter how hard I try I can’t wrap my head around how it would look when they hit each other and ultimately either both fall or one fall, I think it would be really interesting to see what it would look like when they hit each other and what the factors are which result in one or both coins falling down
As usual, that’s some seriously quality slow-mo, keep it up gents!
What is amazing is the bullet left the screen just as the kick back of the gun Dan was holding was just starting. Makes one curious how far the bullet travels for Dan to recover from the kick back and has the weapon level again. That would be amazing to see.
It reminds me how the an-94 fires bullets so fast (with it's special semi auto mode) as to land more shots before recoil hits the user. This video really puts into perspective how viable a concept that was (although it didn't hit mass use for many reasons)
Unless he's an AMAZING speed shooter, the bullet would travel about 100 meters before Dan would be ready to fire again -- that'd be a quarter second split, which I think is pretty close to as good as you can get before you get into competition speeds.
The current world record is .10 second splits (give or take -- it was 5 shots over .57 seconds). In that case, each bullet would travel 40 meters before the next shot went off. (This is ignoring the fact that the shooter wasn't using 9mm, and I'm actually unsure of what caliber he was using, but presumably it was a slower load, so it'll be in the same ballpark as 9mm)

Amazing video as always :)
I'd love to see you guys look at certain workshop tools.
I can imagine it would be rather mystifying looking at how a tool might cut through wood/ metal as if they were butter in slowmotion :)
Been watching since 2012 and haven’t watched a single video of SlowMoGuys where I don’t enjoy it. Always awesome content. Thanks for all the videos and the efforts you put into it.
That comparison side by side really quantifies the speed of the glass breaking. You could have said the speed and it wouldn’t mean nearly as much as something like this! Love it.
Been watching you guys since I was a kid, makes me so happy watching this
I would love to see you guys do a collab with the Hydraulic Press Channel! His slow-mo shots are often inadequate to show the detail of the explosions he creates by crushing things and I think it would be awesome to get your cameras to show some of his explosions in super slow-mo!
I’d like to see the comparison of different types of glass breaking. Like regular, tempered, laminated and even rupert drops.
Regular glass and laminate glass would be pretty boring as they would just crack or fall apart and not explode like tempered glass
@@TheWebster109 and rupert drops are tiny, they would instantly break from one side to the other lol.

I can't believe that when I started watching this channel the technology didn't really exist to watch glass break like this and now we're here
Hearing them talk about the “different” speeds of Mach 1 about how sound moves faster through a solid than through air just absolutely melts my brain
put your ear on a table and tap it
Watching those two arrows race was like watching tyreless Lightning McQueen limping towards the finish line whilst King and Chick raced up behind him 😄
3:28 Dan's explanation here of the speed of sound comparison was so simple and interesting!!
Bullet: faster than sound in air, but slower than sound in glass. I never knew how that worked until now and Dan summed it up so nicely.
That's my one thing learnt for today! I can turn my brain off now (and it's not even 8am hahaha)
Yep that’s how it works. As sound is longitudinal it relies on particles vibrating each other to produce a wave. Seeing as air particles are ‘free’ and there’s lots of space between them, the speed of sound in air is much slower than a liquid or solid, where the particles are always touching. Seeing as they’re always touching it allows for much faster ‘transfer of vibration’. Something that makes a lot of sense but you’d never think of it had someone not told you :D Hope the crude explanation was helpful
@@Lucas-dy4or fantastic explanation, that makes perfect sense! Thank you! 😊
It's interesting that he mentioned the speed of sound because the bullet in the first slow motion was going nearly exactly the speed of sound in air.
@@Lucas-dy4orSound being faster in solid ground can be heard in one video where they were disposing 100 tons of old explosives and when they went off, the camera picked up the rumbling of the exposions through the ground before the shockwave in the air reached it.
Garand Thumb, Kentucky Ballistics, Demolition Ranch would all be great collabs.
Great stuff as always!
Cheers,

I was just going to say with the full range of guns and ammo available to Demo ranch this would be an incredible collab. But you are correct Granad, Kentucky or even the AK guy would make amazing videos.
You forgot Gun Jesus.
@@unfitcheetah I would lean toward Garand as he's really informative with his overviews. And he's kind of in the same realm as slo mo being teaching/learning.
But I'd take anyone tbh.
I like the way the glass stays together for a short time after it is broken ... like done in cartoons for comedic effect.
If I’m ever making a movie I’m getting these guys to shoot the action. They’ve got this perspective on things you don’t usually think about
I love when we get a good relatable speed comparison, more of this kind of stuff is always welcome!
The .220 Swift is a semi-rimmed rifle cartridge developed by Winchester and introduced in 1935 for small game and varmint hunting. It was the first factory-loaded rifle cartridge with a muzzle velocity of over 1,200 m/s, just under Mach 4.
I was just about to suggest this, hopefully they can get their hands on some
Checkout the .22 Eargesplitten Loudenboomer
Doing the math of that cartridge in ft/s (4000 ish) vs the glass (4700ish) the 220 swift wouldn't be quite fast enough unless it was loaded pretty spicy which i reckon could be a tad dangerous. I recommend a Kentucky Ballistics collab.
Its watermelon slowmo time!
@@raygumm its much faster with modern powders the 4000fps load is from the 1930s,, you can reach 4400 with factory ammo now
Amazing video as usual guys of the slow disposition! I'd love to see you film Riccardo Merlini drumming, he's so fast you can't see what's going on... like in the 400 BPM range, it's insane! I know your video's are filmed way in advance, but that collaboration would be amazing.
This footage is absolutely amazing
It's always super cool that glass breaks internally completely before collapsing.
I'm a glass blower and glass cracking is the worst part of my day, but I've always been obsessed with how fast it cracks, I absolutely love your videos on it. I was told by an old timer in the industry that the uniqueness of the sound is that it causes a micro sonic boom, thats why when in our noisy shop and a tiny piece of glass cracks you can "feel" the tink sound from across the studio. I dont know if its true but it sounds quite compelling. I dont know if your resolution at max speed would be able to pick up on that
Since glass cracks at Mach 4.1 It seems reasonable that theres some form of "sonic boom" involved unless I'm way off on my maths
@@Xanderviceory They have made videos of glass cracking in even more slow motion than this.
The initial movement of the glass when cracking far exceeds the speed of sound in air, so it would create a sonic boom. However, the amount of movement is so slight that it probably wouldn't create a pressure wave big enough to see on film. Any sort of sonic boom is a compression event, meaning the sound it makes is not the same as a sound wave...you're hearing and feeling a shockwave rather than sound propagation. That's likely why you're able to feel it from a distance, because shockwaves act differently than sound waves.
@@Skinflaps_Meatslapper woah I've never thought about that. In what way are they different?
@@musiciseverything120 In a visual representation, a soundwave is generally a nice curvy sinusoidal shape, whereas a shockwave is a square or sawtooth shape. Soundwaves are a gradual increase and reduction in pressure whereas a shockwave is a violent and abrupt overpressure event all compressed into a very short burst. The sonic boom of aircraft is basically all the sound that the aircraft makes in flight concentrated into a single pressure wave, so rather than it being spread out over a period of time, it happens all at once. That's why a near supersonic jet won't blow windows out but the same jet flying just a little over the speed of sound will.
This is great stuff. Visually amazing and very educational. 👍
I hear that the cracks in the glass travel faster under water than in air, it would be great if you can test it and see the difference of speed.
It's amazing that the glass breaking is so much faster than the bullet, but the bullet still has a plenty of time to leave the frame before the glass starts falling down.
ok
Yep that was particularly interesting too. The glass falling seemed a lot slower than the bullet, even though in real time it seemed to fall almost instantly.
ok
Atleast the bullet is faster than gravity.
@@coolbluereview - That's probably not the right way to say that since the speed of gravity is considered to be the same as the speed of light.
Well, after converting for fps, your glass is breaking at about 4700 ft/s. There are actually a few sub .22 cal cartridges with factory loads which exceed 4000ft/s, and a couple that are pushing 4500ft/s... I think it would be interesting to see roughly equivalent bullet to glass velocities.
.220 swift is probably the closest you can find with out beeing too niche / boutique altought its been fading ever since the 223s came around
@@glock17games supposedly Hornady's Superformance line have .22-250 and .204 Ruger loads that run 4400 ft/s, and I feel like that's about as fast as you'll get from factory loads.
I also just remembered seeing someone on RUclips loading .300 Win Mag with saboted .223s and pushing over 5000ft/s, so that's another option. (Punched holes clean through 1/2 inch ar500 plate at 200 yards...)
.17 Flintstone Super Eyebunger 4,798 ft/s (1,462 m/s)

@@Necriddarkblade good to hear
I've fired many firearms in my life, it's so cool to see The Slow Mo Guys shoot them in slow mo.
I think the closest rounds you will come close to the speed of the glass shattering are: .17 Remington (or possibly .17 Remington Fireball), .223 Winchester Super Short Magnum aka WSSM, .220 Swift, .224 Weatherby Magnum, .22-250 Remington, and .204 Ruger... most of which are very uncommon rifle rounds. I think the .204 Ruger may have the best chance here based on reloading data in my book.
Yeah. Just read the same article.
G'day, Found this on a quick search from Wikipedia, " The .220 Swift remains the fastest commercial cartridge in the world, with a published velocity of 1,422 m/s (4,665 ft/s) using a 1.9 grams (29 gr) bullet and 2.7 grams (42 gr) of 3031 powder"
That is 46FPS slower than the glass and would vary betweel loads, Atmospheric conditions and firearms used.

@@skullandcrossbones65 get a 26-30 inch 220 swift and it should be faster than the glass
@@WayStedYou G'day, I am satisfied running a .223 Rem, If I think that won't do the job I have a .270 Win that will take care if anything "Down Under".
For those interested, the timing of the glass breaking starts when the bullet is 77% of the way across the span.
I just love you two! Y'all are so great
I remember my high school physics teacher scrapping his entire lesson and taking the whole class to talk about the speed of sound and how theoretically, given the right materials and conditions. sound could travel faster than light. Crazy stuff
The cartridge you'd want to use to compare speed is a .22-284, it's a way overbored cartridge, and loaded with a 60gr bullet they'll hit 4400fps (3,000mph). Lighter bullets will approach and sometimes exceed 5,000fps (3,400mph), so you'd be able to beat the glass in a race with the right load. Also, the lightweight bullets (40gr or so) have a tendency to rip themselves apart soon after departing the barrel, which is why heavier match bullets are the usual load for this cartridge...only a handful of heavily jacketed bullets will handle the speed and centrifugal forces coming out of a 1:7 twist barrel. Having a bullet disintegrate midair would be an awesome thing to capture on camera, but it's an unpredictable event that might happen right out of the barrel, 50 yards out, on impact with a gnat, or not at all. I guess you could score the bullet before loading to make it a little more predictable.
Dear slow mo guys: please listen to this guy! It would be so cool to see a bullet rip itself apart! However: a few tweaks to his request. 1: it might be hard for you to get a 22-284. So get a 22-250 as they are everywhere. Hornady makes a 35 grain ntx bullet in the “superformance” line that will achieve 4450 fps. It still won’t be as fast as glass, but much closer.
Second: if you CAN use custom bullet loads, then please do what he is suggesting as either of these calibers (with custom loads) can achieve speeds high enough to catch this glass, AND have the potential to rip itself apart! That would be so cool to see in slow motion!!
Also: food for thought there are ample rumors that a .17 Fireball in R&D had several test rounds that were vaporizing as soon as it left the muzzle. (Or at least tearing itself apart.)
Please, please try this! Listen to this guy, he knows what he’s talking about, I just added to it. Thanks for the fun content!
Agreed. Seeing a bullet over rev and tear itself apart in slow motion would be really cool. I can easily accomplish this with my 22 creedmoor and light weight bullets. The problem of course would be figuring out when the catastrophic failure will happen.
That would be much harder to find than a 22-250 at 4400fps factory loading
I'm from Texas, only a few hours away from these guys, and I happen to have two guns available in .22-284. I don't mind bringing them out and loading up some real barrel burners if they're interested.
The .17 Rem, .204 Ruger, .220 Swift, and .22-250 can all be loaded to ridiculous velocities, but the .22-284 has them all beat by a good margin. In its introduction, Bob Hutton was getting 6,585fps from a 15gr iron projo and 50 grains of 4227, the iron was necessary to keep the projo intact at those speeds and with the lower density of iron they could keep the weight down while maintaining a reasonable aerodynamic shape. Titanium might be a good replacement candidate for iron if one wanted to recreate those velocities today. It's by no means a practical cartridge, but if you're wanting to launch extremely low BC bullets that look like miniaturized ICBM's at mach 5, or take a small bullet and send it to legitimately hypersonic speeds, it's probably the most practical cartridge you can find.
It's crazy to think spacecrafts go even faster than the speed of the glass shattering
Top speed of the Parker Solar Probe is about 133 times faster than the glass break. Unbelievable
the second visual was absolutely amazing
I know it's not super scientific but I'd love to see how different sized bouncy balls act under different forms of stress, like being dropped vs thrown towards the ground. Or see if it can survive the malteser cannon lol
Slow mo of a bouncy ball hitting a wall after being shot out of the malteser cannon would be amazing
I think it would be cool to revisit this with maybe 5.56 and 7.62x51. Also if you can, the 220 swift is one of the fastest bullets and thus has the best chance to keep up to the glass.
Yup 220 swift will beat it
Published velocity for the 220 Swift is 1422m/s. And the glass was shown at 1436m/s. So maybe on a good shot and a slow break, it might have a chance, but not likely.
Is there a bullet with a velocity of ~4,700 ft/s? About 66.5% faster than the Barret they showed in the short clip at the start. That's what you need according to my terrible math.
@@doshjavis6194 ya . Sorry it would be close . Nothing exact . Depending on the set up barrel , barrel length and other factors it could be faster or slower then the published speed
@@Shezestriakis 22-250.... 1 mile per second....still to slow to keep up with broken glass
6:24 Dan got that light skin stare
6:31 is great. "Bushy Wings" indeed.
The bullet travels by itself, the glass cracking travels at the speed of propagation in the medium of glass
Didn't realize it was that dramatic. Interesting side note -- if you COULD have filmed the nose of an SR71 speeding by at its top speed, the glass would STILL be faster. Truly amazing.
I love Dan's firearm knowledge and discipline.
I love how Dan is still rocking his tattered and destroyed lab coat after all these years 😂
He has replaced it numerous times.
@@workingguy6666 he hasn't replaced it. He uses a different one for their RUclips originals and TV show, but this one is the original. :)
I think he keeps it hermetically sealed between videos.
My compliments for this unique demonstration!

Awesome video. I'm hammered right now, and I was amazed 👏
I would love to see a comparison of how fast glass breaks and bullets travel in water. Honestly I would be curious just to see glass breaking in slow motion under water.
What are you expecting? The bullet stops in a foot or so and the glass breaks at the same speed as in air.
they dont travel in water
It's interesting that the glass holdS together until the entire pane has cracked and THEN it falls apart.
It was falling apart the whole time, but the acceleration due to gravity is quite a small effect on those short timescales.
Exactly my thoughts
It didn’t held together hahahaha it was just cracking extremely fast. It was falling right away, just slow. 9,81 meters per second to be exact. That’s very slow in comparison to the speed of the cracking as you saw
It has to do with energy transfer and tensile strength. For one, it’s clearly tempered glass, as it breaks into much smaller, more uniform pieces. Tempered glass is treated with certain chemicals in the manufacturing process that increases its stress resistance to outside forces. When the glass is broken at a specific point by the pliers, it sends a tiny amount of thermal stress into the glass. That wave of breaking is literally an energy transfer. As it reaches the end, the energy has no where to go, so it most likely dissipates back into the glass in the opposite direction. The same energy that caused it to shatter, now causes it to collapse. Like a rebound effect. If the pane of glass was contained or lined with another material to keep its shape and tensile strength after breaking, the energy would have somewhere else to travel, thereby keeping the glass shattered, but in place, negating the rebound of the energy transfer. There are videos of people doing this for aesthetic purposes.
@@teatimeboy3240 It was not falling at 9.81 m/sec it was accelerating at 9.81 m/sec^2.
That bullet behind the glass scene was so satisfying
Hey guys awesome content. I was wondering if you could do a video about seeing a magician’s trick of changing an object to another in super slow motion lol
Impressive footage as always!
_Our eyes can't see half of the things that are happening arround us...even a bee can fly fast enough to make us wonder what it really was._
Gan and Dav, you two never disappoint.
This is great stuff. Visually amazing and very educational. . As usual, that’s some seriously quality slow-mo, keep it up gents!.
The best thing about this channel is always the shift in reference point you get to actually comprehend how fast certain things are, like bullets and glass cracking to our eyes both just seem instant since they're too fast for us to process, I thought they'd be comparable and would've had no idea otherwise that glass cracking is more than 4x faster, it's fascinating.
Well - that's actually really the second best thing about this channel, the first would be Dan's lab coat.
I honestly thought there would be more collabs with Mehdi… like there are sooooo many things he does on his channel that would look AMAZING in slo-mo.
Would definitely do more
is that the one guy who almost kills himself with electricity every time he makes a video
Says "Toaster in a Bath".
Lol
I think a collaboration with Kentucky Ballistics would be fun, especially when he blows up guns. It would be interesting to see where the actual point of failure is.
@@theslowmoguys PHOTONICINDUCTION!!!!!
You know who he is
You know what he can do
Bring a hammer
A bullet is not a wave, but in physics mechanical waves propagate faster in an object like glass than air.
You could have answered the question even without making a video about it but guys, YOU'RE AMAZING AND I LOVE WHAT YOU DO❤
A .220 swift cartridge comes remarkably close to the speed the glass breaks at. “Fastest bullet in the world vs glass” is a pretty eye catching title.
The glass brakes at roughly 4700 ft/s and the fastest round I could find is the .22-250 Remington. Specifically the Hornady 35gr NTX bullet at 4,450 fps. You might be able to get a hand load up to 4700, maybe.
Imagine Hornady making custom loads to exactly match the speed? That would be a collab!
The thing i want to see is a bullet hitting a tire that is spinning very fast. Sort of like in the movies when someone shoots the tire of the bad guy as he's speeding away. I've always thought to myself "hold on" i'm not sure it would go through that easily, there is too much energy diverting it away at impact. Now i really want to know what happens when a big fat slow 9 mm hits a spinning tire with lots of tread on it at like a grillion fps. Depends on the angle but in the right conditions I don't think it would go through.
I've always kind of wondered about that myself, but never had a wheel that I don't care about just lying around to try. +1 for this idea
Now I need a glass blowing TikTok Collab where you race different glass shapes that double back and spiral
Really cool. A comparison to Destin's baseball gun might be funny😏
I love any of the episodes with the speed of glass breaking, it’s so interesting to me that it shatters so quickly
