I don't really see how 16 year olds driving specifically are particularly dangerous, unless they're driving on the rally track. New drivers in general tend to be less safe due to inexperience, sure, but that's not a specific-age thing.

[@Boosted98gsx]

It's not just fracture mechanics though. It's also modal response of the acrylic as it is vibrated by the force step function. It split apart as those fractures propagated from the vibrations it was subject to.

[@TravisTLK]

Boosted98gsx Yep, that checks out. 😊

[@andrewjohnson6716]

Thank you. That explains why the acrylic panel shattered so (relatively) long after the complete exit of the round. That had been vexing me.

This gun looks like you could shoot someone that's invading the moon. From Earth. In a bunker. 1 mile below the surface. Of the ocean floor.

[@Timeren2010]

The projectile would shatter into thousands of little pieces, the split-second it hit the water. It wouldnt travel more than 1 meter, give or take, depending on angle of the shot. Assuming it left the bunker at all that is... :)

[@jameson8682]

The .50 is a big beast, but Hollywood and the media have given it a bit of an overblown reputation. It'll shred most glass and metal, but it's not magical. A couple feet of hard packed dirt is enough to stop it, and water will turn pretty much any small projectile into a useless lead weight in just a few feet.

I served with the 11th Armored Cavalry Regiment in Vietnam in 1969. We had the M2 Browning 50 caliber machine gun (M1919) mounted on all out tanks and armored personnel carriers. It could easily penetrate engine blocks and as we believed anything else we might encounter. A brutal, effective weapon for the last 101years. It was put into service at the end of WWI and is still in use today.

[@TP-rs5zl]

4:34 Straight up bullet time anime moment, usually when a vital character gets mortally shot, followed up by another character(s) calling out their name, character falling, a monologue, and the character dying in someone's arms, then the camera pans up to the sky... The actual sound from the shot and the window shattering are simply perfect for that moment.

[@DetroitMuscle440]

The turbulence of the poly after the bullet hit and before it left is amazing. Seeing a solid material churn and splash like water is simply mesmerizing.

[@ronlewis8398]

It's funny when you have to play a slowmo video at 0.25 speed to slow it down more. Thanks for sharing. The fracturing of the glass after the .50 was already through was fascinating to watch.

[@WestOfEarth]

That's wild. I think it's plasma ignition - the shockwave at the tip of the bullet compressing the air against the glass to ridiculous temperatures

[@supernoodles908]

@@WestOfEarth I agree

[@8osim]

Maybe it is just a light reflection?

[@bodyno3158]

Boolets do that, a immense amount of heat would be generated upon impact and during the penetration, some incendiary and HE rounds are designed to be ignited by that heat.

[@MHBravo-dn3oc]

_Imagine that the shield wasn’t thick enough, and demolished your camera..._ *NEW TITLE:* What does a bullet impact look like?!

[@user-ds9mx30j6a]

At 0:58 you will see they used a mirror at an angle to make it look like it was headed straight for the camera. No cameras risked taking one for the team in this video😉

[@JRizzo-li2dr]

At 5:59 if you go frame by frame, the very first frame where the .50 cal hits the glass, there is a bright flash of light. Do you think that its the tip of the round heating up to crazy temperatures from the energy of impact being converted to heat, or is something else going on there?

[@PeregrineBF]

Another possibility is sonoluminescence. If the heat/pressure is enough to make the polycarbonate act like a fluid the bullet might cavitate briefly and cause a flash. Just judging by the color a rough estimate (screenshot + CIE 1964 10 degree colour matching function) of the temperature is around 6750 K. That seems low for sonoluminescence temperatures, so simple heating (or some other explanation) is more likely.

[@JRizzo-li2dr]

I like the idea of sonoluminescence. Going back and calculating for KE, assuming he used a 700 grain .50 BMG round (45g at 2978 ft/s), would give the round around 18.54 KJ of energy. Using that number along with the specific heat equation, it could easily get hot enough to melt the glass, copper jacket, or lead. However, on the extremely small timescales I'm not sure if it could overcome the thermal inertia of the materials in order to make them melt. I think we're on the right track, but definitely missing something.

[@-danR]

Even if it _were_ fluidized, the probable viscosity would be orders of magnitude greater than required for expansion and collapse of bubbles.

[@jefferywilliams4533]

It doesn't matter what material that is being shot, a round almost always does this. Another channel here on KZbin, called taofledermaus that usually films exotic shotgun rounds in slowmo has shown this many times. They also don't know why it does it.

[@meritholdingllc123]

[@TerryMcKean]

That was cool, thanks for sharing, SmarterEveryDay and Slo Mo Guys. I'm reminded of some old military training films that show how that half-cone phenomena is 'counted on' in naval warfare when an armor-piercing projectile is fired through the armor-plated bulkheads of a target ship... not only does it pierce through the layers and explodes, it also creates those half-cone fragments out of the armor plating which can travel along and break through the layers deeper inside the target ship.

Triboluminicence when the bullet hits the glass at 5:59

[@willowrabbit]

but what was the darkness after the flash?

[@CheezayBallz]

If too much light impinges on a given pixel in some CMOS image sensors, the potential well of that pixel can spill over and increase the reference level (this is called 'blooming' for CCD sensors). This in turn, causes an error in the sensor's output due to the subtraction of signal and reference. Since the subtraction results in a negative value, the output of the sensor is set to zero. Thus the 'black spots' appear in a field of bright pixels.

[@eaofdeath187]

Well spotted, it's only visible for one frame.

[@Emijoh]

Great eye! I noticed it too once I saw the bullet hit the glass, and had to go back frame by frame to make sure it was triboluminescence. That's not blooming, that's the crystalline structure losing an electron when impacted/split. VERY beautiful! A little disappointed Destin didn't notice it/call it out!

[@raymondmejias8071]

Dude you are so awesome!! Thank you so much for your service and the time you take to make the great work...🙏😇

[@patman0250]

The most interesting thing in this video Dustin didn't even talk about. Right when the 50 touches the glass there's a quick flash at the tip. I wanted to know about that.

[@WhyForWhatNow]

I actually laughed out loud when the 50 cal obliterated the glass 😂

[@ericyao3479]

2:24 I blinked so hard for some reason

[@sinoperture]

That rifle is gorgeous.

Hey, Destin, frustum isn't exactly an old word in the sense of being archaic. We use it in computer graphics to describe the volume of space viewed by a virtual camera. A lot of the calculations that your graphics card does relate to stretching that space to be rectilinear and then flattening it into a 2D plane.

[@Nerd-px7fn]

Here's an idea @smartereveryday. Try shooting (Get it? Shooting?) this kind of thing in the dark. It would be interesting to see if the actual breaking of the acrylic produces any light. Looking for a kind of fractoluminescence effect.

[@andrewjohnson6716]

There is also a mathematical possibility of sonoluminescence.

[@rihamy2nd]

Conner Mong Look at the impact at 5:59 and you’ll see that it does.

[@mediumugly4322]

Conner Mong I posted a similar comment I was thinking triboluminescence clearly there is enough questions to hope he does a video on it

[@darianbrown5098]

I really want that to happen, however gun safety at night may pose some concerns. Hopefully they do make one though.

[@Nerd-px7fn]

Rick M I'm unsure if that's the impact of the metal on the acrylic, or if it's just light reflecting off of the cracks. Hence the need to do it in a dark room.

[@BrendanReagan]

I saw the 50 cal blow him a kiss at about 5:00. The high-speed capture of that happing later? Thank you to both SmarterEveryDay and TheSlowMoGuys!

[@smashOsmash]

Down to the second you guys uploaded! :D

[@TheAceTroubleshooter]

Maybe...over 9000 milliseconds...? :DDD

This was just Destin playing with a .50 cal and making it look sciency. Cool!

Who knew the world of slow motion was so resounding and filled with echos? Is this some sort of outdoor gymnasium? I was under the impression that the sound of these things would be still traveling through the air without having hit the microphone yet at these recording speeds, but there it is clear as crystal, resounding like a tile bathroom. /s

[@skalmelid]

soupisgdfood He made a video about the sound effects a while ago, look it up ;-)

[@smallmoneysalvia]

skalmelid yes, I know. The /s at the end of my comment indicates sarcasm, I was being facetious. It’s kinda funny to think about the effects used and how things like reverberation wouldn’t be able to really happen at these timescales in the same way.

[@skalmelid]

Sorry, the /s for sarcasm was new to me. I wasn't sure if you were serious, so I decided to try to be helpful :-)

[@smallmoneysalvia]

Well, I appreciate the sentiment.

[@smallmoneysalvia]

Jo Blo I love you too

[@user-cq6km9vq2m]

FYI The energy difference between a 9mm and a 50 BMG, is like comparing the power of being hit by an average sized guy, and then being hit by the same guy driving a dump truck.

[@LowLightVideos]

5:37 - Shell shock!

[@Killbayne]

It was like a little *boop*

Two of my Favorite KZbinrs in a collab awesome. 😎 And BTW 7:14 how do we subscribe to this video? 😂

[@kerrybaldino8826]

The mirror breaking after the bullet went through it too was as cool an effect as the ballistic glass.

[@williamrobertingram]

It it just me or does everybody with a super high speed camera also own a 50 cal?

[@odger3700]

Yes. Somehow you´ll have to defend your cam.

[@eddyhernandezventura7350]

No one: Barret 50 cal: making my way through the bullet proof glass like missile danenanene ill kill you denenanene ima reck you

Yes frustums are in play but I don't think the clear dot has anything to do with them. Based on what I know about "bullet resistant" "glasses" they aren't actually one solid piece of material but rather a lamination of acrylic and polycarbonate with an optically clear binder. The reason why that little dot is see through is because the impact energy was great enough to completely pulverize the acrylic face leaving nothing but the polycarbonate backing layer. If you shot pure acrylic the plate would completely shatter and the bullet would go through. If you shot pure polycarbonate it would punch a clean hole and the bullet would go straight through. Only when used in conjunction with one another does the plate begin to develop "bullet resistant" properties. The acrylic face plate shatters on impact; this absorbs and deflects kinetic energy and Increases the surface area of the bullet (mushrooming it), essentially spreading the impact force over a greater area. This impact force is then delivered onto the polycarbonate which acts as a "blanket" to capture the bullet and "glass" shrapnel. I can kind of validate my theory with video footage from 2:48. The visible "murkiness" you see is caused by the different materials flexing different amounts and the binding agent letting go. I use the term "murkiness" for lack of a better word; can you see how cloudy it is? Now take note of the stress fractures (cracks) and compare them to the "murkiness"; notice they have nothing to do with one another. The "cracks" extend multiple different directions and in some instances far beyond the "murkiness". These "cracks" you are seeing are caused by the acrylic separating from itself whereas the "murkiness" is caused by the separation of the rigid acrylic, from the the flexible polycarbonate. More specifically its actually the glue loosing its bond and deforming, this causes refractions and makes it loose its optical transparency. Its the difference between "cracking" in the Xy, Xz and Yz axis. (This of course changes based on your point of view and orientation of the plate but if you read to this point I think you get what I'm saying.) How else could I explain it?... Everyone knows what a mach cone looks like right? Well imagine the mach cone is sand (from crushed acrylic); The bullet is going to transmit its energy into the sand surrounding it, dragging it along as it plows its way into the polycarbonate (essentially fluid dynamics). Also remember that the lead bullet is physically deforming, mushrooming; pancaking if you would. All of this. combined with drag is enough to slow it down to a point where the polycarbonate can flex and act as a sort of catchers mitt. It literally bends and warps to contain the remaining energy. Its awesome. Its the difference between 467 joules of being concentrated on a single point at the tip of the bullet versus spread out over say a nickel-quarter sized area (life and death). This stuff is sort of like tank armour except tanks use ceramic and steel which leaves them vulnerable to HESH rounds (High impact squash head) (basically it turns the tanks armour into deadly shrapnel in the form of spall) (not to be confused with spatter). Hopefully some or most of you know what I'm talking about cause I'm getting tired of writing and am way off topic now but it does lead me to ask the question: why are the inside of tanks not lined with Kevlar; or are they?

[@DrRyan82994]

Worth it depending on where you are hit I think

[@miguelhenriques3308]

caught the frame when the 50 cal. bullet created a bit of plasma right on it's tip when contacting the glass... amazing!

[@Atari-gz6ki]

Nice video! Would have loved to hear more about the fracture cones and how they propagate through the material and what the angle of the cone is for the glass. With the 9mm shot that center point that stayed clear and mostly flawless was a very interesting phenomena. Like the rebound in the middle of a crater impact but untouched. That brings up a question of what kind of elasticity does the material the 'glass' is made of have? Is it several layers of laminated glass together? Some kind of acrylic? I'm hypothesizing that when the 9mm impacted it created a compression perpendicular to the point of impact but did not actually break the glass, however the energy being redirected into the shock of that 'cone' then fractured the glass around it leaving the impact sight untouched. Or the bullet was simply unable to overcome a friction barrier at the surface and when the lead shredded on impact the burred edges dug out the circular crater . OR if it's a laminate material was that impact sight a cleared section of the next layer down? Love your channel man but I'm hungry for more information!

[@siggyincr7447]

They said it was a type of acrylic. My thoughts on it are similar to yours. It looked like the 9mm bullet deformed a cone of material in front of it and as it did the surrounding material had nowhere to go but outwards causing pieces to blow off all around it.
