How much PSI does it take to start a potato?
Pneumatic spud guns are generally more powerful than combustion spud guns. 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 much does it cost to build 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.
How long should a potato gun chamber be?

What’s the best propellant for a potato 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.
How far can a potato launcher shoot?
Potato guns are capable of firing projectiles 500 yards, or even farther.
Are potato cannons illegal in California?
According to California Department of Fish and Wildlife (CDFW) Lt. Dennis McKiver, potato guns are legal under federal law. Under state law, potato guns that use combustion (instead of compressed air) to launch the projectile are “firearms,” and one with a bore of over 0.5 inches is a destructive device.
What is the best barrel length for a potato gun?
A 2″ ID barrel is common for firing spuds but spuds big enough to seal a 2″ barrel are not all that common and tend to be expensive. So, we’ll use a 1.5″ ID barrel instead, most any spud will fit and we can fire other things like crab apples, zuchini, etc.
Are potato guns illegal in Florida?
No Florida law specifically prohibits potato guns. Nor can the government say exactly how many of them exist because the parts are sold in plumbing or home improvement stores and are assembled at home. Without commercial manufacturers to set standards, the destructive potential of the guns varies widely.
Are potato cannons firearms?
All combustion and pneumatic spud guns are considered firearms in every state. Any device capable of being aimed and discharging a projectile using a barrel, and that has the potential to cause injury to a person, is considered to be a weapon and requires licensing.
Are potato guns illegal in Texas?
