I would make something that is spring loaded: pull the spring back, put the tee-shirt (projectile) in the barrel and release the spring. Two moving parts, very easy to ensure nothing can break off and become an unintended projectile.

ts all smoke and mirrors, :^)
The smoke and mirrors idea I like. But with the spring, any sources? And material of the barrel? Largest springs that I can find and replace easily are the kind found on those retractable pens not exactly useful mind.

Team Fusion built this and have modified it several times. After Hurricane Katrina, our t-shirt supply was gone, so a quick change to the barrel allowed us to shoot Hot Dogs into the stands during a pep rally.
I've been following that thread and I think I was the last person to post with an absolutely crazy idea to use a cho-ko-nu (ancient china) to launch the t-shirts. You mentioned video before Hurrican Katrina hit. Do you still have it? May help spark some ideas.


Finally, a couple of you mentioned launching hot-dogs. How exactly does that work?

My understanding is that you wrap the hot-dog in some sort of foil or plastic wrap. Shove it into the barrel, and let it fly. What does the hot dog look like when it lands in the crowd?



Thank you for the quick response everyone. This will make for an interesting spring season.
