T-shirt canon

Later this month I get to have a “anything goes” service. I’m really excited and have been planning. I want to go over the top. If it gets me fired I want this to be something the community talks about for years. Actually my pastor is really cool about things but I’m going to try and push the limits because I can.

One of the thoughts I had was a t-shirt cannon. I have several old youth group tees I’d like to get rid of. I looked into it and those aren’t cheep. They start at close to $1000. Rentals aren’t cheap either but I’ll keep looking around. I am all about DIY so I looked to see if I could find instructions.

I have a spare paintball gun and I am going to try and mod that into a tee shirt cannon. I’m not sure if I can ramp the velocity enough to shoot a shirt a hundred feet or so, but if I can it will be beyond awesome.
~edit~
Research has shown me that a paintball gun will not get enough air so I’ll need a different trigger device. I am thinking I’ll try something like the video, but use my air compressor to fill it instead of a bicycle pump. I can leave it hooked up with a gate valve so after each shot I load the cannon open and close the gate valve then fire again.

Anyone got any advice?
