Building a Penny Shooter

  1. Oct 16, 2007 #1
    Hi,

    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 http://205.243.100.155/frames/shrinker.html but it is rather cool.

    Compressor? What about using CO2 cartridges?

    How far do you think a spring would launch it?
