Diaphragm Valve PVC Air Pistol

Remember the old spud guns from your youth? Remember the difficulty in using such guns, using hair spray, hoping the ignitor would fire the gas, hoping that no failure would occur that would cause the spud gun to explode in a fireball spoiling your whole day? Well look no more for the alternative, the pneumatic Diaphragm Valve PVC Air Pistol, a spud gun made from PVC like its hairspray cousins, but uses compressed air supplied by a standard bike pump, fired from an integral diaphragm valve, making for a safe effective means of propelling projectiles a long distance. With this design you can alter your gun any way you see fit, even going so far as to design all new guns, scale them up to make better versions of the classical spud-zooka, no hair spray required! Build yourself (and your friends) a Diaphragm Valve Air Pistol and have some good ole' shootin' fun!
