. >> it's gorilla floss, for sure. the key is time, temperature and pressure. we found that with increasing pressure ballistic properties went up. the harder we would squeeze it add the right temperature the more the ballistic resistance there was. >> i've got to be honest, it is so light i'm having a hard time believing that this could withstand rapid fire weapons. >> that little piece of plastic that's less than a quarter-inch thick has 400 layers in it. but it's eight, nine times lighter than steal with the same type of stopping power. >> as they say, seeing is believing. we went to a shooting range to test hard wire 's bulletproof being material. starting with a .9 millimeter glock. >> let's turn this into a ballistics challenge. ear plugs in. >> clear. >> definitely hit it. thank you . well? >> nothing penetrated the pack but you can see a couple holes down here writ hit. some of the rounds were deflected down through the bottom. and the ones that didn't go through, there they are. >> they're still hot. >> there's no penetration. the way it's designed, it
