RE: Howdy - TWIH - 01-01-2018
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.”
End of quote
2.7 times the speed of sound? That’s some spud gun!

I play more with black powder but have much respect for air cannons. Some punkin chuckers get miles and have been known to kill crew members during malfunctions.

If we make it there, I hope for a demonstration!
