Re: Optimizing Air Cannon Range

OK, we get our farthest shots when we shoot with the arm elevated to about 40*. 50psi does mid-range shots with footballs and short range shots with the t-shirts. In order to get our t-shirts to travel mid to long range when we shoot them, we have to have at least 80 psi in our cannon, and even up to 110psi to get them to really go.
One thing you have to remember, though, is that when you are at football games, you are shooting into a sea of people, and because of that, you generally want to have your angle be more than 45-50*, so everyone has more time to react, even shooting in large arcs, we have still managed to hit a couple of people in the head. Another good Idea is to have the announcer tell the crowd when you are going to shoot, so they are all looking your way and can't be caught off guard, we do this when we are shooting Shirts, but a simple honk of our horn does well while we are shooting foam footballs and nobody really stands any chance at getting hurt.


We fold our tee-shirts by folding them in half height wise, and then rolling them up tightly lengthwise, we also wrap the shirts in plastic bags with a bit of tape on the outside so they don't unroll in flight, because if we let them unroll, they don't end up flying more than 10 feet.
