Start with the A2 flash hider, comps on a pistol, work their way through comps/brakes on a 5.56/.223 (solgw nox, surefire warcomp, bcm, kac), then a .308, then maybe a .50bmg brake (if available).

That is some of the most amazing high speed footage, plus the "math" on speed I have ever seen... Thanks guys! I've been pushing your channel to both my kids friends and a few teachers... Personally, it is absolutely incredible when you slow it down so far as to see the tempered glass fracture faster than the bullet disappearing out of 'frame" depth wise... It is almost like it's own type of Det Cord...

[@bertkilborne6464]

The shattering of the tempered glass travels at 1mi/sec which is faster than sound travels through air, But could that speed be the speed of sound through glass ?

[@PsychoticBovine]

Interesting question.

[@buckiesmalls]

Speed of sound though glass. 4540 m/s.

[@richardblake2532]

IVE NEVER BEEN SO GLAD TO FIND A CHANNEL/VIDEO THIS YEAR. THANK YOU so much for taking the time to make this!

[@baselsteel4976]

Amazing Very interesting questions :) & truly a fun science experiment * The speed of sound in glass is 4540 m/s (~13 times the speed of sound in air 343m/s at 20C) vs the 1650 m/s speed of crack propagation in tempered glass (that you have mentioned) @ 12:40 the cracks propagated in glass faster than the bullet that was passing in the air above it (it passed it despite the fact that that bullet was shot before the bullet that hit the glass!) *super sonic bullets profile was a nice bonus * throw in a shot gun for some "gratuitous violence" 😂

[@baselsteel4976]

I guess you mentioned the "glass speed" (i.e. the linear propagation of cracks in the direction parallel to the bullet)=1400m/s vs 823 m/s for the bullet (super sonic in air) but I was too mesmerized by the footage that I didn't see it! (definitely want to keep such notes a bit longer on the screen in upcoming videos) 👍

[@ChrisB257]

As usual - this reveals details hardly imagined. Certainly the propagation speed of the stressed glass shattering is amazing. One other thing I wonder is - laminated glass, as per windshield - how much bullet deformation and how much deviation from original flight path, etc. Also, what happens to accuracy when something like a 40cal cop bullet is fired thru windshield from within. Great work guys. :)

[@EVLfreak666]

I would love to see that

[@keeganhenderson24]

This came to my mind to! Cops will shoot through their windshield when needed, so I’d like to see how much the bullet deforms/deflects. And maybe even a non-slomo accuracy test

I've done a lot of informal testing on junk car windshields. I've seen 9mm ricochet off without leaving much of a mark. I think some of the strength is because the windshield is rubber mounted in a steel frame. High speed camera video of this would be great to see.

[@Simp_Zone]

4:58 Holy crap thats a mind boggler of a shot. I'd love to know the relative density of the air molecules just in front of the bullet, since the shockwave is several millimeters in front of it.

[@faded183]

What is that shadow of?

[@LawTaranis]

​@@faded183that's the shock cone. The air density changes so much from the supersonic bullet pushing the air out of the way that it bends light and creates a shadow. If you were to measure the light around that shadow, it is actually slightly brighter than the ambient level.

[@Steve_-ob2ne]

In the dual bullet edge shot at 12:54 you missed something that you hypothesized earlier, which is that the crack propagates "faster than a speeding bullet". Note that the free moving bullet above the glass was leading the bullet that hit the end of the glass, but then the wave from the edge shot beat the free moving bullet to the end of the glass, thus traveling faster than the free moving bullet. This means that the shock wave traveled faster than whatever FPS that .223 round was moving at.

[@edwardarquette3884]

Good shooting with the camera and guns. The one shot was so good the bullet seemed like it was split in half almost perfectly. The visuals were vey cool.

[@lasagner9567]

seeing how all the pellets interacted with each other on impact was interesting for the buckshot. I think hitting it with a smaller shot size like 9 shot from a little further away (to minimize clumping) would be interesting

I was in a car accident years ago and we were sliding sideways at about 80mph when we hit the kerb which caused all the windows on that side of the car to shatter, and I saw that cracking happen in real time spreading across the windows, and when they were completely cracked they just disintegrated and the glass came flying through the car and hit me. It's crazy how fast you can see things when you're in that life or death situation. Watching this video is the first time since the accident that I have ever seen it happen. Brought back memories.

[@david72781]

Great video! I'm a 25 year glazier and have seen a lot of bullet holes in plate, and a ton of shot out windows with tempered. I've cut glass most of my carrier, broken a lot of tempered glass, and know it well. Tempered glass does break faster than the speed of sound. That's why there is a loud pop when it explodes. Pressure is what makes plate glass break more. Smaller, faster projectiles create less fractures because there is less force exerted on the glass. The buckshot is the most exciting on plate because of the more projectiles creating force with every hit. I love glass and I love guns.

[@up4open]

Glass is cooled with Tension inside no matter how it cools. That's part of how it stays clear to us. So what can happen is when you start a break, it doesn't have to break like other solids, it can literally expend all that excess in an explosion that exceeds the amount of force you imparted.
