How far can a potato gun shoot?

Common distances vary from 100 to 200 meters, and there is a reported case of a cannon exceeding 500 meters of range.

What is the best fuel for a potato cannon?

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.

How expensive is a potato cannon?

Introduction: The Original Potato Cannon Sometims it is also called a potato gun. Making this cannon takes about an hour and $30. The finished gun can shoot potatoes over 100 yards!!!

Are potato cannons lethal?

Even your standard potato cannon (usually fueled with hairspray, says MIT’s Technology Review) can be deadly. Recent research found that if you take a potato to the head you have way more than a “50% risk of skull fracture.” Even taking a body shot could do some serious damage and has a good chance of killing you.

Is it legal to make a potato gun?

Pneumatic potato guns that use compressed air are legal as long as they are not used like a weapon (e.g. shot at a person, etc.), so this line-launching device would be legal under state and federal laws.

Can you use gas in a potato gun?

Both propane and butane give off 105 kcal/mol of oxygen, so they should perform equivalently in a spud gun. The article goes on to note that, of common fuels, only hydrogen (119 kcal/mol of oxygen) and acetylene (120 kcal/mol of oxygen) produce significantly more energy under these conditions than other fuels.

What is the best propellant for a gun?

The most effective experimental propellant was defined as the one which accelerated the potato to the highest muzzle velocity. The experimental propellant acetylene performed the best on average (138.1 m/s), followed by methanol (48.2 m/s), butane (34.6 m/s), ethanol (33.3 m/s), and propane (27.9 m/s), respectively.
