Spud guns are small toy guns used to fire a fragment of potato. To operate, one punctures the surface of a potato with the gun's hollow tip and pries out a small pellet which fits snugly in the muzzle. Squeezing the trigger causes a small build-up of air pressure inside the toy which propels the projectile.
