It's crazy how high quality your content is. I remember watching the mythbusters episode on this years back and though their test was super interesting the quality of your content blows it out of the water
So amazing. I’m so grateful for Mythbusters because it paved the way for stuff like this. Knowing these guys grew up on it, now they’re taking it to the next level. I love it.
A few years ago Mythbusters fired a number of rifle cartridges into a swimming pool. All of the high velocity rifle bullets broke apart, even steel jacketed bullets, on contact with the water. Pistol bullets went the furthest in the water. It doesn’t take nearly as much water to protect you from high powered rifle bullets as it does slower moving pistol bullets.
Only thing is, this doesn't really tell the whole story. Some years ago I read through a us army (or maybe it was usmc) study on this. If memory serves it was done in the aftermath of ww2. I seem to recall that testing was on pigs and they tested various calibers. Here's the thing - It's pretty common knowledge that explosions under water are pretty dangerous. Because your meat parts are a pretty similar density to water, the shockwave gets transferred right through you until it hits something with a different enough density and then shreds that. The shockwave from bullets hitting and cutting the water around you basically do the same thing. In the testing, they found a whole lot of damage to the organs, especially the lungs, and blood vessels from pretty surprising distances. Basically, you might be submerged a couple of feet and a burst of 30 cal mg fire hits the water above you. It shreds your lungs and you drown in your own blood without even having a mark on you.
The Mythbusters tried water vs bullets. Rifle rounds self-destruct on contact, pistols penetrate a few feet, and a shotgun flooded their shop by blowing the bottom out of a 10-foot deep tank.
While I was about to make the same comment, I remembered that was almost 20 years ago. High speed has grown exponentially. Also, the shotgun blew out the sides of the Mythbusters tank, not the bottom. The shockwave broke the “glass”, not the slug hitting the bottom.
As I recall, they determined the faster the bullet, the less water needed to stop it because hitting the water at hypersonic speeds was like hitting cement.
@@MH2ga.12 Yeah, that's where they shot the 50 cal... pretty much the same results, the deepest penetration were the slower velocity hand guns and even the 50 cal tore itself apart in the first couple of feet.
Cool video, for scientific purposes tho you guys should increase the vertical depth of the tank. Right now the water can easily be displaced which creates the cavitations. You would get very different results I think if you had a 2 foot deep tank
If/When you guys build another box, don't paint the inside flat white. Go for a 20-30% off-white grey. That way, light interaction with the water will contrast with the background better! Great video, guys!!! Made my lunch break at work more enjoyable! Edit: go Gun-metal Grey!!! Yeah... that'll do...
Man 8.6 blackout would be such a cool round to check out like this high speed. Shot from Q the Fix its spinning 500k rpm. Would be sick to see what that does to a soft target.
14:27 if the second version of the box is V shaped, the water won't expand against parallel walls, it'll just be flung upward, causing less damage to the box.
For version 2 of your box, I'd recommend rather than bolting the plexiglass to the steel box, have it held in place by springs. That way when the lateral force comes, the springs extend, letting out some water and relieving much of the pressure before snapping back into place.
@8:32 yall missed a very cool part about this round, it was spinning so fast and still had so much energy it basically stopped moving forward/horizontall, flipped on axis and the slight pedaling of the round acted like a propeller and the lead round actually went from falling to the bottom to almost exiting the top lol
9:50 As someone who watch a lot of SpaceX lauched, seeing how fast this speed drop put a smile on my face. People have no idea how much is the effect of drag while slowing something down. You see a Falcon 9 light 3 engines and barely slow down from 8000km/h to 6000 while just the atmospheric drag allow bring it down to just below 500km/h when it fires its engines for the final time before touchdown. And here we're talking about air, well...that's water to you, 2600 to 0 in...30 centimeters.
.556/.223 were designed to tumble and dump all their energy within the body. That's why the military chose it in the 1960s. The 7.62x51 caused a lot of damage, but overpentrated before dumping it's energy. I was wondering if it would make it far.
556. is actually great at penetrating body armor. thats why they used it. 556 punches through what 7.62 wouldnt. small hot and fast beats slow hot and big every time regarding body armor. the 556 is accurate out over further ranges than the 7.62. less bullet weight less bullet drop over distance. civilians arent experts on anything firearms related. opinions dont make people experts.
@@nomercyinc67835.56 was adopted before body armor was even thought about being a thing. The only thing that was considered for penetration was Soviet steel helmets at 500 yards with the steel penetrator. (Which wasn't a great feat by any means at all). 5.56 was chosen because more more could be carried by the foot soldier than what could be carried with 7.62x51 and also rifles were more manageable on auto fire than what they were with 7.62x51. 5.56 is only more accurate at distance than 7.62x39, 7.62x51 more accurate than 5.56 at further ranges. 7.62x51 can reach and still be useful at much greater ranges than 5.56 is even capable of obtaining. So guess what Junior you need to read your previous comment in front of a mirror back at yourself and go back to school boy.
@@nomercyinc6783civilians aren't experts on anything firearms related? Thats an ignorant statement. I am an infantry veteran, and I can point you in the direction of a handful of civilians in my area who have likely forgotten more about firearms/firearms related things than you and I could ever learn.

You can't do anything with a bullet in water when it hits the water it's like hitting steel loseing all its energy instantly it may hurt at about a ft But that's it
Thank you for sharing. Too many people have been watching movies and think bullets travel through water… think you have proved it doesn’t take much water to make a bullet none lethal. Shallow end of a swimming pool is enough. Not only don’t bullets travel through water well; they often skip off the surface. This is why they teach you in hunters safety if a body of water is behind your target, don’t shoot.
Supersonic rounds react badly to water... if I remember MB it skipped if you got below about 30 degrees offset. I wonder what a subsonic .223 would look like.
All of these bullets are still very lethal, the energy is being transferred into shockwaves that can travel very far and will transfer through human tissue and then collide with internal organs resulting in severe internal bleeding.
@@qazxswedcxzaqws Think about what you just said a little. How many fish do you see bubbling up to the surface firing a gun into the water? If fish don’t die, then a human will be fine. What you have highlighted can be true for cannons, not firearms. Fish don’t die when cannon rounds impact the water.
@danielcastiglione5328 Fish do only begin to float after they start to decompose. But after thinking about it again the lethal distance may only be just around 3 feet for the largest shockwave underwater due to the small scale of the bullet and the density of the water dissipating it much faster than air can.
@ so you agree the shallow end of the pool is enough to make bullets non-lethal? If you able to do the math on the energy a bullet makes underwater, you would quickly see, no human is going to die from the shockwave from a bullet…. Here is the formula. p = f ( W 1 / 3 / R). The stress of being shot at, far exceeds any effects of the shockwave.
As a fellow Hoosier, I always thought the local scenery looked awfully familiar in your videos. Folding chairs + tripods are the comfiest way to shoot, can confirm
The shooting water episode of Mythbusters was my all time favorite, and later watching Smarter Every Day/Slomoguys do shots underwater captured some incredible footage and unexpected results.
I remember an SAS guy saying you can be shot underwater, with the “experts” saying the opposite. Was surprised by this result, lethal deeper than I would have thought.
Thanks for making this, I also want to appreciate your hard work after each shot. Drying, sealing and Filling the tank again. Setting up camera etc. great content
"X" foot-pounds of energy stopping within less than two seconds means that the energy must be dispersed somewhere. The .308 illustrated that perfectly. The .223 also[9mm... All of them] Cool thing to watch.
I found your channel a short while back when you guys were at around 100k subs, and I immediately knew this channel would blow up very fast. You guys 100% deserve the millions more soon to come
We had a mountain cur (hunting dog) that got in a fight with a beaver in a pond one night. Took at least 30 shots of .22 LR before we finally dispatched him and my brother did it with the last round we had. Now I finally understand why. We were shooting hollow points. Insane!
9:36 Sorry, but I'm a little distracted from the bullets in the water from all that scarring on your arm! Goodness me, I've been wondering what kind of lingering damage would be visible from the RPG episode, but holy cow! I'm very glad to see that arm's still usable.
Is that from an RPG accident? I literally thought he had poison oak all over his arm. Mine look exactly like that when I get caught in it. Takes about 2 months but it goes away completely, no scarring
I'm a .45 guy if for no other reason, nostalgic reasons and respect to some folks no longer with us. When I see, hold, and shoot my 1911, I think of them. I carry a 9mm and I think this video proves that 9mm is a superior round when measured for penetration into the target. I was hoping you would also rest 9mm HP vrs the .45 HP. Very cool video, thank you for what you do.
Pressure only depends on depth, not volume. And as water does not compress a lot, I think depth won’t make a big difference either. But you may have a point because shock waves won’t be able to propagate in a small tank.
try some subsonic rifle rounds too! The real underwater rifles shoot basically darts so longer projectiles at subsonic speeds I think is some part what is necessary for them to keep their speed and trajectory
@@sithus1966 In Private Ryan, I think those were much larger, higher power rounds from gun emplacements, not hand held firearms. Panzerbüchse 38 was an antitank rifle, for example, which could potentially penetrate a lot more water at lethal speed.
I wasn't surprised by this. The ballistics of 9mm is one of the reasons I didn't bother looking at any larger calibers. It has penetration that's actually in excess of what anyone could need at short range and with the right loads you can mitigate that overpenetration to a certain degree if you live in an urban environment. More than enough for self defense, and the recoil is totally manageable.
Myth Busters did some testing in deeper pools, which matters. For every foot down water pressure increases a known amount and therefore your results would vary a lot from your testing method. And who would shoot sideways from underwater? I mean it's interesting but what has it really shown?
@@B.D.B. The actual RPM might not be appreciably faster, but the number of turns per inch (like 1 in 3) is pretty wild compared to everything else out there. And I would think it would be very interesting to see underwater in high speed, especially with something like an expanding copper solid.
Would've loved to have seen some of these rounds more than once. That 9mm FMJ was still cookin at 4-600 fps when it was near the skull. I think that had a good chance of being lethal if it hit
300 ft per second is generally considered to be the cut off for a projectile being dangerous. Of course, that takes into account the size of the projectile. You don't want to get hit by a car doing 300 ft per second!
@@floridagunrat1625it hit something hard enough to ding the copper jacket. At the very least, that should bruise if not break bone. It could still be lethal.
Red Ryder BBs go at 350fps, and are _usually_ not lethal* but will break skin. Now the 9mm bullet is of course much heavier, and thus still can deliver more energy, but spread over a larger impact area. *Exceptions of course apply - not all the brain is protected by nice hard skull bone.
That's very shallow water, so the weight will not generate much pressure 🤔 You should try it again in water a few feet deep and see what the difference is? 🤓 lol
Hmmm. I get the pressure at depth idea, but these (most anyway) slowed down in the first few inches of water. Only the higher powered rifle rounds would have a chance of getting to more depth. But, along those lines, I do wonder if larger box would change results as the pressure “plume” hit the box almost immediately. Shooting into a pool or river or lake would allow the pressure to continue outward longer. If nothing else, the comparison would be interesting!
Seeing that huge volume of water come blasting out of the tank feels like a good visualization of just how much energy is stored in a bullet. It's frankly really impressive.
I think you guys should've done it at around 45⁰ angle. No one shoots straight down to a pool, river, etc. I'm sure if y'all did that, you would cut the distance in half.
The ballistic head makes it interesting, but I'd like to see a re-test where a ballistic gel cube is placed so that there's no where for the bullet to go but into the Gel. Systematically moving the gel cube back will allow for proper estimates of "how much water is bullet proof" for each round.
I’m curious volume comes in to play here like the ripple effect of each of those ripples have very little distance to travel so therefore the concussion is larger whereas if a bigger tank per se or a live situation like a lake or a pool that it would disperse more because of those waves through the water, have farther to travel, instead of coming back and almost creating more turbulence is is so cool to watch being able to see the amount of force that that small bullet is putting it it’s just this small amount of volume of water is amazing. Totally can appreciate all the hard work that goes into making such a video. Thanks for sharing.
This reminded me of my military days. I served in the 80s and my Army issued weapon was the M16 which chambered the 223. It was well known the 223 tumbles when it hits flesh.
When the bullet hits the water in an angle. That is close to the level of the water. The water will not compress but it will ricochet the round. Unless the angle is a little greater. But looking in water and trying to hit something below the surface is like fishing with a bow and arrow for fish you have to aim under the fish to hit it because light refracts what you're seeing. But it might be dangerous to perform for an episode unless you have a wooden backdrop behind the box so if the bullet skips off the water at a low angle it stops the round. To penetrate the water at an angle you need to be up higher than the surface a few feet. Because it's like playing pool with a cue ball bouncing off a rail that cannot be compressed. You can compress air but you cannot compress water the water will move out of the way violently as it is displaced. It's all physics gentlemen. This was an excellent episode 👍👍
Super cool video! Fellow Indiana native here, and I can confirm that we will shoot from whatever seat is available. I've used the back seat of a van before because that's what we had on hand.
That 45 JHP had a really neat effect. After the jacket pealed off it seems like it was able to move faster than the lead core because the lead core was being slowed down by the water while the jacket didn't have much resistance moving through the space behind it. You can see it catch up and try to pop up behind it which was really neat.
The hollow points don't fill with water before they break. All that air is still in them when they hit liquid, or something, well someone, soft, so the differential in pressures causes the thing to expand immediately. Cool stuff, none the less.
You cannot compress water. It's like shooting it at a brick. It expands the round because of inertia imagine dropping a tablespoon of chocolate pudding on your white kitchen floor that's what happens when the bullet hits an object that is made of water or a high percentage of water such as a body. You can compress air but you cannot compress water add lead is softer than water when it hits it at a high velocity and there's a higher mass of water than there is lead. It's inertia hitting a momentarily immovable object of mass at a high velocity
Alright you guys. That was very interesting to watch and see how water an effect of atmosphere and water 💧. Congrats on what you are doing with your craft 👍🏼
Very cool and interesting episode. The slow motion showing the interaction from the water pressure has a lot of value and just looks cool. This is a late post but maybe, in the next box, make the opposite camera side of a flexible/white rubber material to absorb/flex from the water pressure or possibly make just the bottom a flexible material. You could also make a V shape so the pressure is directed at an angle and up but that may affect the view from the camera. I was also wondering if it is possible to make a bullet that could create some short-lived air cavitation which would allow it to flow a little farther under water.
I keep forgetting this absolute mad lad took an explosion to the face, and still does these things. Glad to see you guys kept with it where many would've been too scared to do so! I love your vids
Read something about the D-Day landings, and how some people did tests more recently, with the MG-42 (I think) and how much water was needed to slow down the bullet. And some stories from vets telling how some rounds would bounce off them cause they slowed down enough.
That 1st shot reminded me of the water charges we use to use to breach doors. Slap a stick of det cord on a IV bag and boom instant access. Ahh the good ol days. 🍻🇺🇲
Also, yeah, many suspect the new bullet for 5.56 NATO is really designed to have the jacket fragment and worsen wounding without actually being "hollow point" so it skirts treaties that forbid hollow points/soft points in war.
“Be like water my friends. Water can crash and it can flow. It can take the shape of whatever it’s in. Pour it in a cup it becomes the cup…pour it in a pot it becomes the pot! Be like water.” Bruce Lee. 🐉
The .223 did what it was supposed to: massive cavitation creating a catastrophic injury. It’s not a target round it’s an anti-personnel round… in fact the US forces are looking to replace with a heavier round to counter body armor.
The reaction is exactly Like thunder and lightning. The bullet represents lightning and the trail pockets of displaced Water (not air) collapsing making a sound in the slowmo video is the Thunder that follows

A few years ago Mythbusters fired a number of rifle cartridges into a swimming pool. All of the high velocity rifle bullets broke apart, even steel jacketed bullets, on contact with the water. Pistol bullets went the furthest in the water. It doesn’t take nearly as much water to protect you from high powered rifle bullets as it does slower moving pistol bullets.

correct. pressure increases.
This experiment is in a small contained space . In a place like a lake or river the cavitation would not be 1/10 in that distance .
If you are 36” below the water surface ,you are pretty much safe from anything fired here.
Just seeing the reaction of the bullets going through water , and the delay between sound and all the detail.

Maybe. But kinda better because it's not over dramatized like myth busters they are just straight to the point
One of the, if not THE best channels on RUclips! Easily #1 for high-speed and guns!! I just love watching these videos!
Thanks for making this, I also want to appreciate your hard work after each shot. Drying, sealing and Filling the tank again. Setting up camera etc. great content
The audio in slow mo is satisfying 😁❤
"X" foot-pounds of energy stopping within less than two seconds means that the energy must be dispersed somewhere.
The .308 illustrated that perfectly. The .223 also[9mm... All of them]
Cool thing to watch.
I found your channel a short while back when you guys were at around 100k subs, and I immediately knew this channel would blow up very fast.
You guys 100% deserve the millions more soon to come
Full wadcutter 38spl would be interesting.
We had a mountain cur (hunting dog) that got in a fight with a beaver in a pond one night. Took at least 30 shots of .22 LR before we finally dispatched him and my brother did it with the last round we had. Now I finally understand why. We were shooting hollow points. Insane!
You got my sub when you followed up with the m855a1 after the .223. Awesome video
9:36 Sorry, but I'm a little distracted from the bullets in the water from all that scarring on your arm! Goodness me, I've been wondering what kind of lingering damage would be visible from the RPG episode, but holy cow! I'm very glad to see that arm's still usable.
Is that from an RPG accident? I literally thought he had poison oak all over his arm. Mine look exactly like that when I get caught in it. Takes about 2 months but it goes away completely, no scarring
Love this channel. I am also very happy and grateful to see him doing so well since the accident. That takes one strong person. Respect.
I'm a .45 guy if for no other reason, nostalgic reasons and respect to some folks no longer with us. When I see, hold, and shoot my 1911, I think of them. I carry a 9mm and I think this video proves that 9mm is a superior round when measured for penetration into the target. I was hoping you would also rest 9mm HP vrs the .45 HP.
Very cool video, thank you for what you do.
15:10 Indiana represent! I even thought it looked like an Indiana country road and house earlier in the video! 😂
I've ALWAYS wondered about this topic. Thanks for saving me from boredom during long hours spent on the tractor BHS!
We do what we can!
Shooting into a pool, the water pressure is going to be higher. The bullet box doesn't have enough volume.
Pressure only depends on depth, not volume. And as water does not compress a lot, I think depth won’t make a big difference either. But you may have a point because shock waves won’t be able to propagate in a small tank.
@@didfet5496Mythbuster already did that.. long story short if you want to survive a shooting just jump into the lake or river and swim away.
Under water dome shot, YES PLEASE!
Great video guys! 👍🏼
That video-camera camera 📹 is the ish 👌🏾 🙌🏾 💯
That last shot was awesome!😮😮😮
try some subsonic rifle rounds too! The real underwater rifles shoot basically darts so longer projectiles at subsonic speeds I think is some part what is necessary for them to keep their speed and trajectory
Excellent video. This busts the myth of the 7.62x39 bullets zipping through the water 10-20 feet down in Lethal Weapon movie…..
Or the rounds killing the soldiers underwater in Saving Private Ryan.
@@sithus1966 In Private Ryan, I think those were much larger, higher power rounds from gun emplacements, not hand held firearms. Panzerbüchse 38 was an antitank rifle, for example, which could potentially penetrate a lot more water at lethal speed.
@@jrhoadleythey were being shot at with mg 42s from a good distance who knows if they would have enough power
I wasn't surprised by this. The ballistics of 9mm is one of the reasons I didn't bother looking at any larger calibers. It has penetration that's actually in excess of what anyone could need at short range and with the right loads you can mitigate that overpenetration to a certain degree if you live in an urban environment. More than enough for self defense, and the recoil is totally manageable.
It is clearly the change from air to water, the speed decreases as the ammunition moves towards the normal straight line. this is beautiful
Myth Busters did some testing in deeper pools, which matters.
For every foot down water pressure increases a known amount and therefore your results would vary a lot from your testing method.
And who would shoot sideways from underwater?
I mean it's interesting but what has it really shown?
I miss that show. 😔 🙁
Seeing the bullets spin made me think of how cool it’d be to see 8.6 blackout in highspeed with the 1:3 twist barrel
It wouldn't be spinning any faster. The twist rate is high because the velocity is low. The actual spin rate is comparable to "normal" cartridges.
@@B.D.B. The actual RPM might not be appreciably faster, but the number of turns per inch (like 1 in 3) is pretty wild compared to everything else out there. And I would think it would be very interesting to see underwater in high speed, especially with something like an expanding copper solid.
Would've loved to have seen some of these rounds more than once. That 9mm FMJ was still cookin at 4-600 fps when it was near the skull. I think that had a good chance of being lethal if it hit
Agreed
300 ft per second is generally considered to be the cut off for a projectile being dangerous. Of course, that takes into account the size of the projectile. You don't want to get hit by a car doing 300 ft per second!
@@floridagunrat1625it hit something hard enough to ding the copper jacket. At the very least, that should bruise if not break bone. It could still be lethal.
Red Ryder BBs go at 350fps, and are _usually_ not lethal* but will break skin. Now the 9mm bullet is of course much heavier, and thus still can deliver more energy, but spread over a larger impact area.
*Exceptions of course apply - not all the brain is protected by nice hard skull bone.
Ok. .
That's very shallow water, so the weight will not generate much pressure 🤔 You should try it again in water a few feet deep and see what the difference is? 🤓 lol
Hmmm. I get the pressure at depth idea, but these (most anyway) slowed down in the first few inches of water. Only the higher powered rifle rounds would have a chance of getting to more depth. But, along those lines, I do wonder if larger box would change results as the pressure “plume” hit the box almost immediately. Shooting into a pool or river or lake would allow the pressure to continue outward longer. If nothing else, the comparison would be interesting!
Wow I really love this video, it really tells me what I tell some people, that 9mm has a much longer travel distance then the 45 👏👏👏👏👏
This was fun to watch. You can tell you guys had fun making it and the video clips are amazing.
Seeing that huge volume of water come blasting out of the tank feels like a good visualization of just how much energy is stored in a bullet. It's frankly really impressive.
It's insane how much energy a small little piece of lead can have, honestly.
3+ feet and you are golden 95% of the time. Water OP
I think you guys should've done it at around 45⁰ angle. No one shoots straight down to a pool, river, etc. I'm sure if y'all did that, you would cut the distance in half.
The ballistic head makes it interesting, but I'd like to see a re-test where a ballistic gel cube is placed so that there's no where for the bullet to go but into the Gel. Systematically moving the gel cube back will allow for proper estimates of "how much water is bullet proof" for each round.
I’m curious volume comes in to play here like the ripple effect of each of those ripples have very little distance to travel so therefore the concussion is larger whereas if a bigger tank per se or a live situation like a lake or a pool that it would disperse more because of those waves through the water, have farther to travel, instead of coming back and almost creating more turbulence is is so cool to watch being able to see the amount of force that that small bullet is putting it it’s just this small amount of volume of water is amazing. Totally can appreciate all the hard work that goes into making such a video. Thanks for sharing.
Fill that thing up with liquid hydrogen and see how far the bullet goes through
CALL OF DUTY please take notes I should never be killed underwater again!
This reminded me of my military days. I served in the 80s and my Army issued weapon was the M16 which chambered the 223. It was well known the 223 tumbles when it hits flesh.
When the bullet hits the water in an angle. That is close to the level of the water. The water will not compress but it will ricochet the round. Unless the angle is a little greater. But looking in water and trying to hit something below the surface is like fishing with a bow and arrow for fish you have to aim under the fish to hit it because light refracts what you're seeing. But it might be dangerous to perform for an episode unless you have a wooden backdrop behind the box so if the bullet skips off the water at a low angle it stops the round. To penetrate the water at an angle you need to be up higher than the surface a few feet. Because it's like playing pool with a cue ball bouncing off a rail that cannot be compressed. You can compress air but you cannot compress water the water will move out of the way violently as it is displaced. It's all physics gentlemen. This was an excellent episode 👍👍
Super cool video! Fellow Indiana native here, and I can confirm that we will shoot from whatever seat is available. I've used the back seat of a van before because that's what we had on hand.
That 45 JHP had a really neat effect. After the jacket pealed off it seems like it was able to move faster than the lead core because the lead core was being slowed down by the water while the jacket didn't have much resistance moving through the space behind it. You can see it catch up and try to pop up behind it which was really neat.
Man idk how this channel doesn’t have at least a million subscribers yet
The hollow points don't fill with water before they break. All that air is still in them when they hit liquid, or something, well someone, soft, so the differential in pressures causes the thing to expand immediately. Cool stuff, none the less.
You cannot compress water. It's like shooting it at a brick. It expands the round because of inertia imagine dropping a tablespoon of chocolate pudding on your white kitchen floor that's what happens when the bullet hits an object that is made of water or a high percentage of water such as a body. You can compress air but you cannot compress water add lead is softer than water when it hits it at a high velocity and there's a higher mass of water than there is lead. It's inertia hitting a momentarily immovable object of mass at a high velocity
Alright you guys.
That was very interesting to watch and see how water an effect of atmosphere and water 💧. Congrats on what you are doing with your craft 👍🏼
Great content, so cool! And yes to bigger calibers and underwater head shots, absolutely
Mega! So stunning and informative. Very good footage and quality. Thank you for such a superb episode. 👍🏼👍🏼
Slow mo is art🤩❤
What I love about your video.Is shows if you're at least 3 to 4 feet on the water.You will not get hit by the bullet
Skip to 3:40
Water tank soo much cooler than balistic gel, there is so much more to see! Good Job!
Thank you guys for this very interesting high res vid!
one of the coolest videos I have ever seen. Thanks guys for sharing.
That was so badass. Love watching and learning from you guys.
Great vid, but I think for a more accurate study, the tank should be fixed to the ground to prevent lateral motion when the bullet meets the water.
Very interesting.... I like how you don't waste time on one scene... It makes me watched everything
my favorite part of the slow mo is the spinning fragments leaving behind a spiraling trail.
Very cool and interesting episode. The slow motion showing the interaction from the water pressure has a lot of value and just looks cool.
This is a late post but maybe, in the next box, make the opposite camera side of a flexible/white rubber material to absorb/flex from the water pressure or possibly make just the bottom a flexible material. You could also make a V shape so the pressure is directed at an angle and up but that may affect the view from the camera.
I was also wondering if it is possible to make a bullet that could create some short-lived air cavitation which would allow it to flow a little farther under water.
I keep forgetting this absolute mad lad took an explosion to the face, and still does these things. Glad to see you guys kept with it where many would've been too scared to do so! I love your vids
It be interesting you could measure the hydrostatic pressures transferred to the water. Also appears harder bullet hits more water pushes back
Read something about the D-Day landings, and how some people did tests more recently, with the MG-42 (I think) and how much water was needed to slow down the bullet.
And some stories from vets telling how some rounds would bounce off them cause they slowed down enough.
Really cool stuff guys! 👍
That 1st shot reminded me of the water charges we use to use to breach doors. Slap a stick of det cord on a IV bag and boom instant access. Ahh the good ol days. 🍻🇺🇲
13:12 it's more mass. It's thicker, it's longer.
Best video I've seen in a long time. Amazing.
Also, yeah, many suspect the new bullet for 5.56 NATO is really designed to have the jacket fragment and worsen wounding without actually being "hollow point" so it skirts treaties that forbid hollow points/soft points in war.
“Be like water my friends. Water can crash and it can flow. It can take the shape of whatever it’s in. Pour it in a cup it becomes the cup…pour it in a pot it becomes the pot! Be like water.” Bruce Lee. 🐉
The .223 did what it was supposed to: massive cavitation creating a catastrophic injury. It’s not a target round it’s an anti-personnel round… in fact the US forces are looking to replace with a heavier round to counter body armor.
The reaction is exactly
Like thunder and lightning.
The bullet represents lightning and the trail pockets of displaced Water (not air) collapsing making a sound in the slowmo video is the Thunder that follows
You boys are putting out good content!💪🏿💪🏿💪🏿
Awesome video guys. I would love to see a tracer under water, that would be cool. I can't wait to see what's coming next from you guy's.
