how do I make a potato canon?

Answer 1

"Potato canon or guns" or "spud guns" as they are known consist of sections of PVC plastic tubing and fittings and are designed to launch a muzzle-loaded potato (or other similar-size projectile) using hair spray or other aerosol vapor as a propellant. The propellant is ignited by means of a barbecue grill igniter or other similar ignition system.

Laws regulate certain weapons as "destructive devices". These have to be registered .However the provisions excludes from the definition of "destructive device" any device which is neither designed or redesigned for use as a weapon and any device, although originally designed for use as a weapon, which is redesigned for use as a signaling, pyrotechnic, line throwing, safety, or similar device.

Potato guns" or "spud guns" as described above have been examinednand it has generally been determined that such devices using potatoes as projectiles and used solely for recreational purposes are not weapons and do not meet the definition of "firearm" or "destructive device" Such devices have been classified as "firearms" and "destructive devices" if their design, construction, ammunition, actual use, or intended use indicate that they are weapons.

Possession and use of "potato guns" or "spud guns" may be restricted under State laws and local ordinances. Further, any person intending to make, use, or transfer any such device must be aware that they have a potential for causing serious injury or damage.
