| картофельная пушка (A potato cannon (also known as a spud gun) is a pipe-based cannon which uses air pressure (pneumatic),[1][2] or combustion of a gaseous fuel,[3][4] to launch projectiles at high speeds.[5] They are built to fire chunks of potato, as a hobby, or to fire other sorts of projectiles, for practical use. The projectile can be dangerous and result in life-threatening injuries, including cranial fractures, if a person is hit. wiki Alexander Demidov) | |||
