CHEMISTRY?

Aha. A more sophisticated bomb. A 20 oz. pop bottle. Fill the bottom with pieces of rolled up aluminum foil. Pour The Works toilet bowl cleaner into the bottle until the level of cleaner is slightly above the level of aluminum foil. Screw the cap on tight. Shake. Shake hard. When the botle starts to get taught, set it down and run. Be warned, when the bottle explodes, it sprays hydrochloric acid all over. It even creates fumes (sometimes) that are so powerful it made me cough hard. The gas created by the reaction is hydrgen. Obviously, this creates some startling opportunities, given that hydrogen is EXTREMELY flammable.
