Smash! Bang! Boom!
You've probably heard of rubbing two sticks together to make fire...
How does it work?A Texas-based chemistry professor recently made a “smashing” discovery when he wrapped two rusty, high-density, steel spheres with aluminum foil. Smashing the two together resulted in the release of heat energy along with a surprising bang and spark. This reaction between the rust (iron oxide) and the aluminum graphically illustrated the chemistry of the classic thermite reaction.
