If you’ve ever fired a potato cannon, you’ll know that they are a raucous good time, but are somewhat clumsy to reload after each shot. Seeing an opportunity to improve on the design and minimize the delay between launches, [Danger First] have concocted a fast reloading potato cannon — or should I say — Potowitzer.
The key here is that they’ve gone through the extra effort of designing and building honest-to-goodness artillery rounds for their Potowitzer’s manual breech-loading mechanism. Foregoing the inconsistency of potatoes, they’ve 3D printed a bevy of bullets and sealed them with propane gas into PVC pipe cartridges. Metal contacts around the base to carry current from a BBQ lighter to the inside of the cartridge to ignite the propellant. Seeing it fire at about 18 rounds per minute is something special.
This home-made piece of artillery looks like a blast to fire. The only issue appears to be that the rapid salvos are offset by the necessity of fabricating more ammunition — something that isn’t an issue with regular potato cannons. Remember to exercise all necessary precautions if you plan on using any kind of combustible.
If you want to get an idea of what’s going in inside these rounds — or the chamber of a regular potato cannon — check out this tennis ball cannon with a clear combustion chamber.
