And a student at a militry academy bet his friend that a kevlar vest would stop a knife-lost the bet, and died from the chest wound. I guess its one of the edge geometry phenomena-
Dance like you have never been hurt, work like no one is watching,love like you don't need the money.

Do not use plexiglass to try to stop a bullet. LOL

If you want bullet-resistant glass buy it.

To do it yourself I think you're gonna have to do your own testing. Obviously, you can save a ton of cash doing it yourself. They got it priced like it's a racket. Lexan and Plexiglass are not very expensive and the hurricane films you can buy cheap online. The film is just cold pressed laminate, which should cost about 20 bucks for a 100' x 3' roll, but you'll pay closer to $100 or 2. Although, if you are a masochist and getting fleeced "makes your day," then you can spend a thousand dollars or more. The sky is the limit on a lot of these plastic products, but if you shop you can find them cheap. Although, you will have to do your own testing. Moreover, if this isn't for "personal use," then I reckon you could open yourself up to a lawsuit. Otherwise, I don't see a problem and if it's gonna save a life, who cares. Most businesses and individuals cannot afford products that are marketed as bullet proof glass and I reckon courts are aware of that. I mean, if the choice is between something or nothing, well, that's obvious.

Basically, they seem to recommend layering it, with just about any combination of materials or all the same. Still, I bet a solid piece of 1/2" Lexan with 8 mil film on both sides would stop cheap street rods, but I haven't actually tested it yet. Also, for testing, you can find companies that sell "cut offs" from large sheets they trim for customers. That is the cheapest way to buy it. A lot of these morons are just carrying 22s or maybe a little 38. You know, it's a throw away pistol. lol

To test it, you call around, you can probably find a range that will let you. As a matter of fact, they'll probably want to be there! Unless, they've already done it twenty times themselves.

Plexiglass is o.k., but it isn't as strong and it cracks too easy when you work with it. So, it's kind of a pain. Still, they use it a lot in the "real" bullet resistant glasses. Which is kinda funny, because technically, air is "bullet resistant." lol

I don't remember if somebody already said this, but when a bullet is stopped by plexiglass the glass shatters and sprays little shards of plexiglass out. Lexan doesn't do that. So, it is superior and surprisingly, it isn't that much more expensive. Still, you'll see them combo plexi with lexan in professional bullet resistant glass. Usually though, the plexi is sandwiched between lexan. I guess it saves a little money.

I have absolutely no experience with "bullet resistant glass" but I did just read an interesting test report on it with great pictures on "The Box of Truth" website found here http://www.theboxotruth.com/docs/bot6.htm

This is a great site for answering questions about firearms and bullets, worth checking out.
