My Team has constructed a T-shirt Cannon, which got tested for the first time today. We had a very anticlimactic result has the T-shirt basically just fell out of the end of the tube. We are using the KOP pneumatic system connect to about 1.5 foot ABS tube. The tube has a inside diameter of 3". I know we do not have enough pressure behind the T-shirt. I was wondering if a smaller diameter tube would fix this issue? We have our pressure built up to 110psi, which I thought would be enough to at least get 20 yards. Any help on this would be greatly appreciated!
