Bamboo gun
From Wikipedia, the free encyclopedia
Bamboo gun is a traditional toy gun made from a hollow cylindrical piece of bamboo and a piston works as a syringe plunger. A tough small "bullet" like a dry seed or a wet piece of paper is inserted in one end of the cylinder and the piston is pushed in rapidly at the other end. This results in the air compressing inside before it pushes the "bullet" out with a pop.
Today, the material of the gun barrel is modified from bamboo to alloy.
