I feel like this channel is secretly funded by a curious assassin.

Love how the glass mist as it travels around the bullet looks in slow motion. I wonder if you had different colored panes of glass how the colors would mix, would you be able to identify different layers from it's color creating a rainbow effect or would it all mix together?

I'd love to see this done with heavily colored glass, so we'd know if the fragments of glass are pushing through each piece. It would also be beautiful I'm surprised the bullet fell behind some of those shards in velocity as well

These guys are one of the core channels of KZonlines and what it used to be. I'm glad to see them adapt and continue this good content. Love it!

A slomo of chainsaw cutting would be interesting - to really see how the tooth cuts. John Adler does a great job explaining the theory.

I think this experiment would be interesting if they used panes of glass of multiple colors (eg, red, blue, yellow, orange, violet, etc.) to track what glass remnants continued moving forward and at what point those glass remnants stopped. In other words, would any glass shards move between the panes (or would they be deflected by the next pane) or if they did move at what point would they stop and at what rate would they stop.

Gav, I will forever love when you edit in the speed of an object (i.e. 4:33) so we can visually understand how much something's momentum is changing as it moves through the frame. It's stuff like this that makes your editing so bloody enjoyable.

3:07 I LOVE seeing proper handling of guns!! Just the «safe» thing really made me happy for some reason.. respect for weapons is important!! They’re deadly if you can’t use them properly..

If you guys ever do this again it'd be super cool to space the last pane out further so you can see the bullet bounce off with less of the debris in the shot, though that would probably be super difficult as the bullet sort of changes trajectory. Still incredible footage you guys capture with this one.

You're actually able to see the stages of deformation on the bullet through each layer of glass, that's crazy

You guys do an exemplary job with the sound design. In all of your videos. So kudos, really well done.

I love these videos, where you can really see Dan's military knowledge shine through.

I appreciate your continuing to keep Dan’s gun safety call-outs in the edit for each shot. 👍

Awesome video as usual guys :) But I have to say I loved the beard interaction around the 14:15! That's awesome... made me laugh :) Don't think a lot of people caught that one :)

These boys show us fun and physics in a beautiful way. Thank you gentlemen. That last shot, with the bullet coming 'at me'.. you captured something special with this one.

i love that either from his time in the military (or his own curiosity and edification) dan is able to provide all this insight into bullets in this video and the tiny gun shooting the bullet video

One of your best films ever, boys. Simple and glorious, with all the angles and moments I wanted to see, and plenty of time committed to the actual slow motion shots as usual. 10/10

For those familiar with ballistics, this is what happens with a low standard deviation. When you've chosen a brand of ammo that has a very consistent speed between one shot to the next, consistent bullet weight from one shot to the next, your impact energy is also going to be quite consistent.

I always appreciate hearing Dan going through the steps of safety with the gun, there's no joking about it and it's not removed from the edit.

I really like the sound design in this video, it really adds so much

I would love to see slow motion shooting comparison of bulletproof glass and other materials like lexan, acrylic and polycarbonate if you haven't already done such a video. It would definitely be cool to see the different characteristics of each material as it's being impacted.

You guys were very helpful used your data to calibrate the ballistics in our game how much a 9mm slows down in glass. Thanks a bunch! (Please do a 5.56x45 and 7.62x51 now ♥️)

I would love to see you guys tackle non newtonian fluids, especially shooting at them.

It would be interesting to see this done using double glazed units. Would the vacuum between the panes make a massive difference?

The absolute legends out here continuing to deliver the most fascinating, wholesome content around. Never change, lads.

This last mirror shot was insane, like death coming for you. Great video like always, thanks. Maybe there are kinds of glass that do not shard as much for better visibility of the bullet? idk.

One of the most interesting takeaways for me was that the intermediate panes take a lot of damage just from the shrapnel of the preceding pane. I hadn't expected that.

I would love to see the same experiment, but using jacketed hollow points.

I am imagining that if the panes of glass were clamped together, that the results would be so different, but just as interesting. 😊

This would've looked even cooler with stained glass shots too. Get the right lighting set up like with that mirror shot and you might be able to catch the reflections of the pieces of glass as they fall and shimmer, plus you'd get to see a lot of cool color combinations with lens flare

Honestly just seeing how much each glass pane decelerates the bullet really helps visualise why ceramic armor plates are so effective.

I love the wonderment in their voice. After all this time and all this content they're still curious and fascinated by their findings. Cool video

This has to be one of the most satisfying videos you’ve made. Good job guys, keep it up!

This video is one of your best ever! Spectacular and surprising results. Well done.

Really cool stuff guys!! Appreciate Dan’s gun safety as well ✌🏻

You guys are awesome! This footage is amazing! Well done!

You can tell these two are best friends and equally as interested in the projects they do when you hear them simultaneously say "wow" at seeing the bullet bounce off the pane of glass at 12:19. The best part is knowing there are thousands of other people who joined them in that moment for that exclamation of wonder.

It would have been interesting if you put all the glass pieces together (no spacing) to see if it would have made any difference.

That shot of the bullet heading towards the camera, even though it's only a mirror, is I think the coolest clip to ever come from this channel. It's so cool it seems like it should only be possible with VFX but it was done for real by just 2 dudes and some glass.

I'd love to see this done again with a copper bullet vs the lead fmj. You could compare the number of panes, loss of velocity per pane and see if the dust clouds react differently

Could be interesting to put all the sheets in comic book bags or maybe a saran wrap layer? Love the content! You guys are awesome!

Immensely entertaining! Wow guys, loved it, keep it up!

As much as I like seeing Dan play the goof who always ends up in a pratfall or something silly like that i really like these moments where he shows off how knowledgeable he actually is. Telling us about bullets, or his knowledge of explosives. It's just cool.

There's a way to view the stress patterns in glass with a polarized light source and a polarizing filter on the camera (making a field-expedient polariscope). The strain pattern shows up as a beautiful and usually quite chaotic looking rainbow. Since you now have a camera fast enough to show glass breaking at a reasonable speed, could you try rigging up such a system and showing glass being both impacted to the point of flexing but not breaking, and also show it breaking? I think the strain pattern both under pressure and as it breaks would be quite a show.

2:03 The more numerous smaller particles are slowed down more by the air, and act more like clouds because of their interaction with the air, while the larger particles, at first hidden in the cloud of smaller particles, are less affected by the air, and so stay moving faster for longer and move on more ballistic trajectories.

Would've loved to see 10 panes with one in every other slot. I feel it would've taken fewer since the glass would lose more power over the larger gap, thus making the bullet impart more energy on each of the panes. Would be cool to see this acted out.

Видео получилось очень крутым и качественным!!! Продолжайте в том же духе)

I wonder if you would be able to see the bullet bouce more clearly if you separate the 11th pane of glass from the 1st ten? Very cool to see!

Looks like you did a great demonstration of the space armor effect. The spacing allows some of energy to dissipate. It would be nice to see a control where the glass plates aren’t spaced.

That was really cool to watch , good job guys .

AWESOME!!! I love how well it captures the bullet going through the glass.

Have you considered using laser beams that the shattering glass would interfere with? And if you polarize that light it might provide additional visual details.

I would like to see the same test with a much larger spacing between panes.

i think it would be interesting if you used something like a perfect layer of ballistics gel to slow the bullet down before impacting on a similar pane of glass. Maybe that would allow you to get a much cleaner shot of the bullet bouncing off the glass, without all the excess glass from previous panes. Although the glass fragments did make for excellent slow motion footage.

In terms of usefulness and information, you guys are actually extremely helpful to vfx artists as your videos are excellent reference footage

I'd love to see this done with a monolithic copper bullet!

2:22 "I think I underestimated how powerful a 9 mil round is" Indeed. It can, after all, blow your lung out of your body.

I think the cuts on the board were off center because you guys' chop saw blade was pivoted at a slight angle (Maybe about 22.5? Probably less than that) You should be able to adjust it to 90 degrees straight on. Usually you pull a pin at the base of the saw head and the blade itself angles. Also if you keep the saw down for more than a split instant, the groove it makes will be wider and less curved. I absolutely love this video, but I couldn't stop thinking about that.

One thing I would love to see you guys do is rapid fire two or more rounds to see how the trailing rounds react

I LOVE that mirror shot, looks like some nutty practical effects for filmography.

Dan says about destroying a GoPro "Was I the last person to do it? I shot one with a cannon" in the same way I'd say "Do we need milk? I bought some yesterday." What a gloriously odd life these two lead.

Have you guys ever looked at water jet cutting? Would slow mo capture anything? Just a thought. Love the chan!

I wanna see this again, but space out the 10 panes of glass through the whole width. I think there'd be less chance for the glass to break the nextpane, and you'd see more of the bullet impacting, and also I think it wouldn't go through as many panes. Great shots, though.

windshields also deflect bullets on account of being laminated - they're actually 2 panes of glass adhered in the middle, which is why they stay intact and wobble when they break. It's not only structural strength, but stops glass from flying directly into drivers and passengers.

love the bullet bolistics ideas. lots of fun on the gun range to have with different amo like expanding and armor perching

Would have been absolutely interesting to see how many glass panes a intermediate and a full-powered round would have gone through.

This was definitely one of the best slow-mo uploads

One thing they didn't mention, which I thought was really interesting, is how the bullet only deformed/broke up after it had *lost* most of its energy and was traveling far more slowly. That's not what I would've expected at all. Also, it would be interesting to see what if any difference there would be with the panes stacked closer together or further away. Sometimes you can see the next pane flexing as shards hit it from the previous one, ahead of the bullet. I'm wondering if, at certain distances, the bullet is hitting the pane while it's flexing towards it, which would make it harder for the bullet to break it. If that's right then at different distances between the panes, the bullet may be hit a pane as it's flexing away from it and therefore be more able to break it.

Very interesting and entertaining. Thank you for covering the ground for better cleaning!

This show is the perfect intersection of art, science and entertainment.

Great video, best part was when the glass threw itself away. Very earth friendly glass.

Need to do this again with different types of 9mm bullets like Lehigh defense extreme penetrator and some sort of hollow point. Would get different results due to bullet construction I would imagine

Not a big deal, but windshields aren't tempered. They're made of two pieces of normal, untempered glass that is cut then bent into windshield shape, then a layer of plastic (polyvinyl butyryl) is inserted between the glass layers and the entire sandwich is put into a giant autoclave (a pressure cooker, basically) where it melts and fuses the lites together. You can tell it's not tempered because windshields will chip or crack but don't explode in the way that a side or rear window does. You want the windshield to break and cave in but not explode in the event that either a sizeable object or a person hits it from either side. Source: Worked in a factory making auto windows, including windshields - broke enough of them to know tempered vs not

Now I just want to watch Dan run through 11 sheets of plywood in slow motion, Daniel Craig style

That last shot made me gasp! Gav you're a genius. Also Dan is lethal with that pistol.

Quite interesting indeed :D I am not a scientist but, to me I'm pretty sure one parameter got overlooked in this experiment, it's the space in between the pieces of glass 🤔 I mean, I imagine there is some kind of supporting effect, meaning the next glass is supporting the compressed air from the previous one. This is probably partly the answer to why the first glass stays standing with just a little hole and a crack when you have 20, but not when you have 3. When the bullet passes through, the shockwave transfer to the next "air slice" but the support of the following glass makes it compress. In short, the bullet is slown down by her own shockwave. I think that's what we see as the "Matrix liquid glass" effect 🤔 Probably the bullet could go further if the layers were spaced out, and stopped way before if the layers were closer 😁 Just a thought 🙏 EDIT: I can imagine that this isn't linear either, there is probably a point where the "air slices" are too thin to compress at all, allowing the bullet to go further until there is a sweet spot where the opposite happens. Like obviously, if you would stake the layers of glass directly onto each other, this might stop the bullet in only a couple of layers 😅 Anyway, I gave already way more thoughts than I should to this 😂 Thank you guys 🤗

May not be something available in 9mm, but it would be interesting to see how much difference a solid copper, vs jacketed, bullet makes.

That was great guys. I would really like to see a magician doing a faro shuffle close up in Slow Mo.

While watching this I was wondering what percentage of the glass dust from the first pane made it through to the end, perhaps a follow-up experiment with colored glass could elucidate that?

I want to see an improvised body armor tested. The idea is taking a phonebook that is about an inch thick and placing about 5-10 pieces of sheet metal throughout the phonebook. If you can harden every other one. Then see how it compares to an AR plate weight wise (maybe weight per square inch). Then do something similar with several layers of Kevlar between the sheet metal instead of the phonebook (but target the same weight).

Winshields are also laminated with at least two panes held together by polyvinyl butyral (PVB), which makes it "bouncy". Slightly elastic deformation on top of the rigidity and external pressure resistance of the tempered pane.

Id like to see a rapid firing weapon in slow motion. I'm curious what that would look like would they all be in a row or spread out and would they be spaced evenly apart or would they travel at different velocities.

Initially I thought it would have no problem breezing right through 20 pains of glass however after watching the first part and seeing how much 10 pains has slowed it down I'm kind of beginning to wonder about that and I'm going to continue watching this video just to find out now LOL

the face on footage was incredible ..thanks for doing what you do.

“Let’s be honest, when have we ever given something useful?” Dudes, I’m certain Hollywood absolutely loves you for these videos cause you’re able to slow everything down considerably and give other researchers information they’ve never had before.

It would have been more awesome if you guys also showed us the deceleration rate on the succeeding shots as well. Just based on my observations, I'm almost certain that it's not consistent with the first shot where it started at 806mph and dropped to 50mph on the 10th pane. Why? Because the succeeding shots landed a bit higher than the said first 10 panes, making them a bit tougher to penetrate so it should have a significant effect on its deceleration, miniscule or not, I'm really interested in finding out how, if at all, big of a difference each shot made if it landed on different spots.

Have you guys ever thought about trying to film a minigun? I think the high speed spinning and bullets exiting the barrels could be spectacular 👍🏻👍🏻👍🏻

Should have done one with the panes spread out like every other one. Since the first bunch are being broken by the 'blast' and not the bullet. Would be interesting to see how many panes the bullet breaks without that assistance.

Thanks guys, I love this channel. Seeing the bullet plough through so many layers of glass, slowing down a bit at each one, reminded me of this scene from "Blade Runner" where the replicant Zhora is shot but keeps on running: kzonlines.info/up/o62rn5i7pJ2mZ6c/bejne She's the bullet, but she didn't make it through quite as many panes of glass, faltering at the end like a spent slug.

It'd be interesting to see if the same result was achieved (11 panes) with different spacing. From a 2 inch gap to no gap... 🤔

I have to say, in the slow mo shots Gav’s attention to each little clink and crack with his sound design is on point as always 👌🏻

know what might be a cool shot? Putting some distance between the 10th and 11th panes, maybe that could create more separation between the bullet and the shards before it bounces off. Just a thought. Love the video!

AMAZING! Simply gobsmacking amazing! Bloody well done!

This is a beautiful display of matter in extreme environments! Well done 👍

This is more or less a reminder for how dangerous standard window panes actually are and why we use tempered, laminated and/or safety glass literally everywhere else

If you could find a non shattering medium to slow it down so it actually bounces off glass in a clear shot, that would be phenomenal

I didn't even realize the suspiciously grown beards in between shots until you drew attention to them. I take it the last shot couldn't be made for a bit? Otherwise this was exceptional. Watching physics in motion like this is visual poetry. That mirror shot was pristine!

You should change the density of the glass. Use the same thickness of glass, sandwich the panes together and see how many the bullet will go through. Also, you'll want to do the opposite, by spacing them farther apart than you have them now.

officially the coolest thing you guys have ever done, that last shot.

I love how ‘Fluid’ the glass looks as it follows the bullet through. It’s like a glass tail on a lead bullet comet.
