T-shirt launcher

  1. Oct 30, 2012 #1
    I have to build a t-shirt launcher as an engineering project using only mechanics, no pneumatics or pressurized air. Can anyone give me any ideas on this? Right now my idea involves a pvc pipe and resistance bands inside as a slingshot. I want to use a trigger to release the slingshot but im not sure about how to go about doing it.

    Take a look at the release mechanism on a crossbow.
