Amateur Scientist Builds Thermite Grenade Cannon (gizmodo.com)

Posted by EditorDavid on from the flash-powder dept.

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.

    1. Thermite is perfectly legal to own. It is not regulated by the ATF whatsoever.

    We made it in high school chemistry class. Here is the recipe:

    1. Powdered aluminum
    2. Powdered rust
    3. Mix
    4. Ignite
    The stuff does not explode. It just burns, and produces molten iron. We did it on a 1/2" steel plate out behind the school, and it burned through the steel.

    Notes:
    1. Our chemistry teacher was really cool
    2. Always wear eye protection when doing stuff like this.
