Can 45 layers of bulletproof glass -- 45 layers that combine to make a 40 centimetre thick bullet stopping wall, mind you -- survive against a RPG-7 rocket launcher? The idea is to find out if it's possible to use bulletproof glass to armour a tank against anti-tank weapons such as a RPG.
Crash Zone did the test and though the bulletproof glass held up admirably (I mean, a rocket is being fired at it), it didn't quite work. Even using armour that was spaced out from each other couldn't survive against an RPG. Still, it's fun seeing a rocket get shot at glass and cause a cool explosion burst.
