Amateur Scientist Builds Thermite Grenade Cannon (gizmodo.com)

YouTube personality Colin Furze has built a homemade cannon which he's filmed launching grenades filled with thermite, "an especially nasty chemical composition made of metal power and oxide that burns as hot as 2,500 degrees Celsius." Furze once co-hosted Sky1's program Gadget Geeks, and he's since made a new career demonstrating strange science projects on YouTube. Furze's other homemade devices have included a rocket-powered go-kart and a knife that can also toast bread while it's cutting.
