Potato
The potato (aka spud) is the original and most common ammo for a spud cannon. This is largely an effect of their low cost and availability. Due to using a spud cutter to cut the potato to size, they have a nearly air tight fit, to the point where it can prevent loading. (a solution is offered here)
Use and target performance
Typically large and juicy ones are preferred, as the size is needed for larger barrels and the juice acts as a lubricant in the barrel when muzzle loaded.
Upon impact with:
- A twig, a potato typically survives.
- A water-filled milk jug, a potato is reduced to "potato crumbs"; small bits of potato only a few mm in size.
- A tree, a potato is reduced to "potato crumbs".
- A rock, a potato is reduced to "potato crumbs".
specifications
