people use the works toilet bowl cleaner, or drano to make stuffty bombs.
these cleaners contain HCl (Hydrochloric acid), and a number of other tasty chemicals. When you combine this with certain metals such as Zinc, or Aluminum (aluminum foil), a chemical reaction takes place where a nice amount of hyrogen is created. if you get enough of these reactions going in a confined space, there starts to be too much too fast, thus explosion.
2 liter bottle, 1/8th full of aluminum foil balls, then fill it with a whole bottle of the works cleaner, close it very quickly, 1 shake, throw, run. you have to get away FAST right after its closed, i've had one go off within 5 seconds of closing it.
dont be stupid, it could really hurt you if it went off next to you. i take no responsibility for injury/legal stuff.
