Re: Air Cannon
WOW! I'm glad I asked this question. I definitely didn't know parts of this were so dangerous. We are changing to ABS or a non-PVC tank and will do extensive safety tests.
Ours doesn't launch with lots of power. At a 45 degree angle and 110PSI, a shirt goes approximately the height of a 2 story house. Last Thursday, we tested it by first hitting a mostly empty trashcan, which it did not knock over (but did rock). One of the parents then volunteered to get hit at close range (10ft) and was fine. Then some kids got hit at catching distance and were fine. The lack of extreme power in our launcher may be due to the barrel being so much larger than the tank and the shirt not being too tight in the barrel (allowing air around it). We'll try to be careful and scrap the plans if it looks dangerous.
For those that do launch at football games, pep rallies, etc. what other safety precautions have you taken?
