Made me read up on Wiki about spud cannons, I didn’t realize it was so technical. Imagine this:
“The highest projectile speed recorded from a spud gun is 933.3 m/s (3,062 ft/s) (approximately 2.7 times the speed of sound) with a 16.6-gram (256 gr) 20 mm plastic slug from a hybrid using a 20 MPa (2,900 psi) pre-ignition mixture of air and propane.”

2.7 times the speed of sound? That’s some spud gun!
