MP4 | Hi-Def | Blip | YouTube | PDF | Subscribe Sometimes it can be so frustrating to have people you want to give a T-shirt to who are far away and inaccessible on the upper decks of stadiums. They wave their hands in desperation with such hope and joy at the possibility of receiving a T-shirt from you, but you know in your heart that they won't, because your throwing arm just isn't capable of hurling a T-shirt into the upper decks ... Fear not, your problem may be solved this weekend if you attempt to build this awesome air-powered, solenoid control valved, tough-looking T-shirt cannon! I collaborated with William Gurstelle, author of Whoosh, Boom, Splat. It's fun and exciting to work with Bill! Sponsored by Ponoko: Ponoko is a new concept that's perfect for Makeziners.
