What is a good accelerant for 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.
What fuel do you use for a potato cannon?
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 much propane does a potato gun use?
When making a traditional potato or spud gun, the propellant used, some sort of aerosol spray, is pretty forgiving when it comes to consistent ignition. While we didn’t do any experiments ourselves, generally 5% propane to 95% air is the best ratio for generating a bang.
