7 Deadly Weapons You Should Never Ever Make Out of Harmless Household Items
Having done 1, 3, and 4 in my teenage years I would definitely concur. Especially the thermite, that stuff will burn through the hood of a car, then the engine, axle, pavement, and dirt below it. Heinous stuff. However when you need to cut a large steel pipe and you don't have an acetylene torch it will do the job. Also, don't forget filling a tennis ball with match heads. That one is not only extremely flammable but completely uncontrollable and unpredictable.
