Holly Holm potato gun

WATCH: Holly Holm fires potato gun

Watch former UFC women’s bantamweight champion Holly Holm fire a large potato gun. WikiHow says the gun, also called a spudzooka, potato cannon, and spud gun, make for an entertaining project that also demonstrates a few laws of physics along the way. Part of the thrill of constructing a potato gun comes from experimenting with the basic design to get the best performance, all while learning valuable engineering lessons.

A combustion-based spud gun has three basic components: an ignition source, a fuel chamber and a barrel. When the pressure in the barrel overcomes the resistance from the potato, the expanding gas forces the potato down the length of the barrel and into the air.
