Powerful Golf Ball cannon! [Black Powder in a 1.75" fiberglass tube] (2013x22)

Data di messa in onda: Giu 27, 2013

This cannon was pretty extreme. It shot a golf ball at speeds approaching the speed of sound and has some SERIOUS power. We typically used around 1 ounce of powder charge, enough to propel the ball clear through a bucket, and into the dirt. Electrical ignition was not bothered with, used long fuses instead. Your right Chemcam, it is a PITA :P
