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..

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.

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

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

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

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

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

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

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.

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

Love the content. Cheers from Estonia

The good bulletproof glass is aluminum, oxygen, and nitrogen (ALON/aluminum oxynitride) and glass layered.

LOVE THESE VIDEOS!!

>video about making bulletproof *glass* >looks inside >resin

I love these videos so much!

Shoot the glass side. The reason is the poly-c side is used to prevent glass flying at the people it is designed to protect. Of course you can put plexi on both sides, but you could put tempered glass over the plexi on both sides for clarity and scratch resistance.

The dollar signs to hide the gun for demonetization was funny, well done lol

What? Why would you re-anneal toughened glass? Any glass supplier will be able to provide annealled glass, it's just standard glass. Surely that would be cheaper/faster/easier.

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!

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

On par with the OG bulletproof video!!!!!

You should frame the glass first to hold all layer together and prevent the glass from flying around

love this video!

fun fact for not the gun junkies, green tips are armor piercing rounds with a steel core, really good at penetrating things

outside view is for fancy only. try metal sheet walls (steel container, can) filled with concrete or plascrete (resin + sand in concrete style mix), yep bulletproof glass is just concrete block roughly. try kinetic sand inside a steel can.

you should make a suit of armor out of bulletproof glass

I feel like it needs to be mounted to a frame to actually test if its bulletproof. A lot of energy was lost when the front piece came off the Big Mac.

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

5.56 mm not .556 caliber

Frame, they need frames to prevent extreme separation.

nice vid 👍

Polyvinyl Butyral is a type of resin, it is also called polycarbonate

Great Video Guys if you can understand how armor platting is made on a WW2 Battleship built proof glass is made almost in the same manor with different types of layers of protection .. On a Battleship the Armor - Plating on different parts of a Battleship the armor plating has cement between the armor plating to absorb an in pack from a heavy shell you were close to making armor plating do a little homework and do a revist Happy New Years Guys

You should try to do the same thing, but whit the glass mounted inside a car door to see how the glass and door ends up looking.

They reallh should have used a tarp for all that glass.

<a href="#" class="seekto" data-time="849">14:09</a> it's 5.56 OR .223. and GREEN TIP = Green-tip ammunition is most common in 5.56/. 223 Rem caliber and is mainly designed for use with the AR platform. These rounds were originally considered controversial, as they meet one of the criteria of the federal definition of armor-piercing ammunition.

<a href="#" class="seekto" data-time="107">1:47</a> thank you, i never knew what they were saying

<a href="#" class="seekto" data-time="11">0:11</a> That room and lighting reminds me of the "I feel fantastic" video

I wonder how it would go if one were to alternate between layers of acrylate and glass, so as to have a cushioning effect between layers and thereby offer some form of damping effect.

Quality internet video

Technically a waterjet video

As a guy who works for in a glass shop, taking tempered glass and making it into annealed its the expensive and hard way. 3/8 plate glass shouldn't be hard to get. Even 1/2 shouldn't be hard to find.

Just use 10cent penny as spacer. This should be one problem solved :D

Is this channel really about showcasing the many versatile uses of resin?

You're supposed to shoot the glass side. If you shoot the polycarbonate side, the glass explodes off the other side and into the face of the person you were trying to shoot. Aside from that, I think you may have had better test results if you had bolted the glass into a steel frame that compresses the glass together as well, since the glass would be installed into a building in a similar way. It would help to keep the layers from separating when you shoot it.

I'm wondering something, if it was held in place, maybe it would have made a different result ?

Video is a yes indeed

Good sir you need PVB as a inner layer 😂 finally get to telll someone!

Usually we want bullet proof glass, because our face is going to be on the site opposite from the bullet. I'd say in this case we want the glass to be the strike face, because otherwise we get a face full of shards. EDIT: yup

Time to play with different resins to see what's better 🤷

No. You can however, try to make 'Bullet Resistant' glass.

I lost track of this channel. I used to watch them back in middle school. Whatever happened to the OG weirdos that founded this channel?? These guys just don't hit the same

Please please please make a full window!

cool video

I defiantly want to see you try this again with the proper binder, or hell just random different binders. What would a thick ballistics gel do?

How did you clean up all that glass? 😮

<a href="#" class="seekto" data-time="130">2:10</a> muted it as you explained about glass and didn’t realize it 🤣

Reading ".556" hurt lmfao

Use lexan as first plate and last.. Its more flexible.

My brain quits working at this time of year, so no sciency stuff and have a happy new year guys.👍

how u do all this and not research the correct strike face

On the question of the title. No, it not possible to make bullet proof glass without experience since you building experience while making the glass.

Need more gun vids

Should have put something behind the glass so we could see the potential damage if we try this at home 😂😂😂

You should have used a jelly resin

Now will the glass lasagna stop a rocket?

you should do something like this with slowmo guys

It's 5.56mm, not caliber - the caliber version is .223.

Wow hot off the press.

Very cool video. Now I know .556 is the way to go.

yes it is

You're doing real science here. This is like Myth busters and it's awesome.

You could have cut some of those jokes. But I am glad you didn't.

on the real tho... you arent leaving a bunch of glass shards in the forest are you? you dont know the amount of glass I have hauled out of places.....seems a tarp or tarps would solve that

What happened to the original 2 guys on this channel?

Don't go hiking barefoot behind Bountiful… 💀

Damn i miss the old crew.

The glass is to spall in diameter

Impressive 🤔

the ".556" had me dying bro lol 5.56

Some bulletproof glass is transparent aluminium

Oh that's why it didn't survive you shot it with a .556 caliber gun You're supposed to use a 5.56 mm gun

Holy crap, is that Marvin Gaye?

I can cut wood with my hand¡???

nice

YES DADDY we love BULLETPROOF glass that was a huge thick layer at the end

Do you have a percinal channel?

Resistant*

I hope you cleaned up all the glass shards you left in nature

Bro said M855 green tips were standard ".556 caliber"

what is blud yapping about <a href="#" class="seekto" data-time="416">6:56</a>

I wonder if using hot glue would work well as the binding 'resin'

wow

Make it with hot glue instead.

22LR?

What the F is .556 caliber

Why is he doing that with his eyebrows? <a href="#" class="seekto" data-time="396">6:36</a>

Ya frame it up next time

LOL it would not have stopped the 30 06 even if it was the first shot they are way way more powerful than 556. Higher velocity and much heavier. 556 223 are basically faster .22 rounds with more weight and not much more weight 22 250 are faster and same weight as a 556 but 30 06 beats both in terms of penetration energy dump all of it
