I Made Bulletproof Glass With Basic Materials

Stopping green tip is nothing to scoff at, there are even some hard body armors that can't! You sounded sarcastic about the "wicked" 5.56 but that chunky boy was thoroughly bullet proof.

Soon as you mentioned the resin being soft I had an odd thought. Can you make bullet proof candy? Layers of brittle with taffy or melted licorice between? ... Its a strange morning..

PVB is similar to double sided clear tape. Unlike the resin you used it remains flexible more like rubber than plastic. When using it to laminate glass you place down a sheet of glass then apply the pvb sheet to the glass then lay on the next sheet of glass and apply heat and pressure to remove air bubbles. It does not take much heat or pressure to do it. A hot plate turned on after the glass pvb sandwich i laid on it with say some ply wood and a cinder block laid on the plywood is enough pressure and let the hot plate heat up to a couple 100 deg f will be more than enough then you turn off the hot plate and let it all cool down. To rig it up for shooting it for testing you would want to make a wooden frame around it and a dense rubber material say archery target matts or rubber mudflap material between wood and glass around the edge of the BP glass panel. You can screw the wood together

Epoxy is a suboptimal resin for binding glass for this purpose. "Resin" comes in a thousand different varieties and PVB is more like hotglue rather than 2-component epoxy.

Framing the glass and also having polycarbonate on both sides would have really helped it stay together. Just incase theres a next time.

I'm pretty sure bulletproof glass is usually held in place. Therefore, does not expend momentum moving

The polly carb goes on the back to contain the glass fragments instead of spraying them towards the stuff/people your protecting.

FYI some ballistics information here, the green tip 5.56mm used (also not .556, that would be over a half inch in diameter, its actually .22cal just going very fast) is green due to the designation M855, which includes a small steel penetrating tip that did much better than a full soft projectile.

The fact that it stopped anything at all is kind of amazing.

Love the content. Cheers from Estonia

LOVE THESE VIDEOS!!

You're supposed to shoot the glass side that way the pieces don't get blown apart because the polycarbonate is what keeps the glass together and not shattering into your face after it's been shot as you saw in your second shot of the bulletproof glass you made

I love these videos so much!

love this video!

Id definitely explore using a more rubbery resin like you mentioned in the video.

"A piece thick enough it could be a mom in a pixar movie." ...😂😂😂

The back layer on commercial bulletproof glass is poly to collect spalling. If glass side was the back it'd send shrapnel in - it is visible in the first successful piece you made! E: I needed to watch like a minute more! HAH!

>video about making bulletproof glass >looks inside >resin

you should make a suit of armor out of bulletproof glass

I've seen lots of things on YouTube, I don't think I've seen anyone make bespoke bullet proof glass. Please continue down this physics rabbit hole. For my own enjoyment.
