A pneumatic potato cannon A large pneumatic design: The projectile is loaded in the muzzle (not pictured), which is then attached to the cannon (at 2). The air reservoir (3) is filled to 120 psi (0.83 MPa) using the Schrader valve (4). Upon opening the solenoid valve (1), the air from the reservoir is transferred to the projectile, which is ...
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.
Lead bullet being supported by a wooden cup sabot in a Delvigne gun. A cup sabot supports the base and rear end of a projectile, and the cup material alone can provide both structural support and barrel obturation. When the sabot and projectile exit the muzzle of the gun, air pressure alone on the sabot forces the sabot to release the projectile.
Pneumatic cannon. Pneumatic cannon may refer to: Dynamite gun, any of a class of artillery pieces that use compressed air to propel an explosive projectile. FN 303, a semi-automatic less-lethal riot gun. Holman Projector, a naval anti-aircraft weapon. M61 Vulcan, a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled ...
A hail cannon is a shock wave generator claimed to disrupt the formation of hailstones in the atmosphere. These devices frequently engender conflict between farmers and neighbors when used, [ 1 ] because they are loudly and repeatedly fired every 1 to 10 seconds while a storm is approaching and until it has passed through the area, yet there is ...
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 ...

Most aluminum cans are made of two pieces. The bottom and body are "drawn" or "drawn and ironed" from a flat plate or shallow cup. After filling, the can "end" is sealed onto the top of the can. This is supplemented by a sealing compound to ensure that the top is air tight. The advantages of aluminum over steel (tinplate) cans include;
