Toy physics - Pop guns-- cork, potato, or foam poppers // Homemade Science with Bruce Yeany

Fun and easy instructions for several variations of pop guns,potato poppers, and pop gun repeaters are shown in this video. The science behind the toy is an application of the basic concept of Boyles law. The relationship shows that as the volume of a gas is decreased the pressure will increase. An increase in pressure becomes great enough in the toy barrel to expel the stopper at the end of a tube with a very satisfying POP.
