I'm looking to find a way to build an air cannon of some sort or perhaps something I can hang from the ceiling. I'm directing Cinderella as well as The Drowsy Chaperone and would like to find a way to create something that I can either use with an air compressor or perhaps a vacuum based cannon. Either way our theatre is not doing well financially and we cannot afford to buy or a machine or rent one for two productions. Any pictures, articles, or folks you could link me up with that would know how to do this would be very helpful or perhaps a philanthropist who'd like to loan a cannon out for cost of shipping. Thanks again!
