Thermite

A small pile of thermite looks harmless until it decides to eat through steel like it's cotton candy. This high-temperature blend of metal powder and oxide produces a reaction so hot it does serious damage wherever it's placed, accelerating the destruction of your target. Ideal for when you want to commit arson and host a science lesson at the same time. Wanna know how jet fuel melts steel beams? Add a little of this to your arson repertoire and find out. Just stand well back after you've lit this stuff.
