How do potato guns work?

A spud 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. Squeezing the grip causes a small build-up of air pressure inside the toy which propels the projectile.

How much force does a potato gun have?

A typical combustion gun generates average chamber pressures of about 30 psi (210 kPa) with peaks of around 70–100 psi (500–700 kPa), while the average pneumatic gun can operate at pressures in the vicinity of 100 psi (700 kPa).

How hard does a potato gun shoot?

Potato guns are capable of firing projectiles 500 yards, or even farther. A 2013 Colorado study found that acetylene propellant potato guns can achieve a muzzle velocity of 138.1 m/s, approximately 310 miles per hour. In short, potato guns are very dangerous.

How does a potato gun work What pushes the potato plug out?

When firing a spud gun, the user first pushes a potato past the barrel knife and all the way down the barrel. Once in place, the potato acts as a seal at the end of the fuel chamber. The spark ignites the fuel, causing an explosion. Pressure builds rapidly behind the potato, which is wedged tightly in the barrel.

What’s the best fuel for a potato gun?

A more powerful option is to drive the potato using the process of combustion and the rapidly expanding gases this creates. Indeed, combustion-driven potato cannons are simpler and easier to build then pneumatic ones. Perhaps the most popular fuel for such a device is hairspray, which often contains butane or propane.

Is it legal to make a potato gun?
