Potato cannon. A potato cannon, also known as a potato gun or potato launcher, is a pipe-based cannon that uses air pressure (pneumatic), or combustion of a flammable gas (aerosol, propane, etc.), [1][2][3][4] to fire projectiles, usually potatoes. [5] A simple design consists of a pipe sealed on one end, with a reducer on the other end to ...
Garbage disposal unit. A garbage disposal unit (also known as a waste disposal unit, food waste disposer (FWD), in-sink macerator, garbage disposer, or garburator) is a device, usually electrically powered, installed under a kitchen sink between the sink's drain and the trap. The device shreds food waste into pieces small enough—generally ...
Spud gun. A typical factory-made toy die-cast spud gun. The cap attached to the muzzle converts it into a water pistol. A spud gun or potato gun is a small toy gun 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 in the muzzle.
Automated vacuum collection. An automated vacuum waste collection system, also known as pneumatic refuse collection, or automated vacuum collection (AVAC), transports waste at high speeds through underground pneumatic tubes to a collection station where the waste is compacted and sealed in containers. Full containers are transported away to be ...
The action, or the mechanism by which subsequent rounds are automatically reloaded, must also be powered by the air pressure; that is not a major drawback as pneumatic tools such as the nail gun proves as long as you carry an air tank and compressor around with you. The weapon has to supply or be supplied with a source of very high pressure gas.
Vacuum bazooka. A vacuum bazooka is a pipe-based cannon which uses a vacuum pump (often a vacuum cleaner) to reduce pressure in front of the projectile and therefore propel a projectile as a result of the air pressure acting on its reverse. The concept was originally proposed by Neil A Downie in 2001 [1] but many variations have been built ...

M61 Vulcan. The M61 Vulcan is a hydraulically, electrically, or pneumatically driven, six- barrel, air-cooled, electrically fired Gatling-style rotary cannon which fires 20 mm × 102 mm (0.787 in × 4.016 in) rounds at an extremely high rate (typically 6,000 rounds per minute). The M61 and its derivatives have been the principal cannon armament ...
