Steam gun: Friction heated water in a tube shoots a cork. A small amount of water is introduced into the gun barrel. A cork is pushed firmly into the muzzle of the gun. A friction clamp is attached. The water in the gun barrel is boiled by applying friction with the hinged wooden clamp held in hand. The cork is shot out. TEMPERATURE AND EXPANSION.
