Building a Penny Shooter

  1. Oct 16, 2007 #1

    First of all, I highly doubt this is in the correct forum so move it if necessary. I've been at this forum for a while although I never really bothered to post anything. The other day however, I decided that I wanted to build a penny shooter, or a gun that shoots penny's into maybe watermelons or items of that nature. The problem is that I am having trouble finding ways to accelerate the penny. A compressor would be too big, so my guess is that pressure is out of the deal. Any ideas from you guys?

    Try using a compressed spring, and see how much effective it is. It can be dangerous, though.

    You probably don't wan to start building one of these on your own but it is rather cool.

    Compressor? What about using CO2 cartridges?

    How far do you think a spring would launch it?
