I was out testing my bowling ball launcher to see the difference between using 1/2 lb and 1 lb of Tennessee exploding targets aka Tannerite. The test almost went bad when it launched at an angle back towards my truck! lol
American Guns TV show built a bowling ball cannon out of an Oxygen Cylinder in one of the episodes. I think they charged the customer something like $12,000 for building it.
Looked cool and worked fine but I would have built my own for CHEAP and spent the rest of the money on something else.
thanks guys! this was just an idea I had a while back and was made out of scrap metal for free. I cant believe someone would pay $12k for a ball launcher, thats insane! hell even $1k for one would be crazy! lol
