A couple of weeks ago I was in Pennsylvania with Jeff and Sean, and you know what that means. Destroying things in order to building things which will eventually be used destroy things. A few months ago Sean got a long and very thick steel pipe in at the scrap yard. He saved it aside until Jeff and my next visit with the plans of turning it into a cannon. This sounded pretty dangerous to me so I, as always, was prepared with my camera, just in case anyone got hurt. Have you ever had the experience of hearing such a loud sound that it actually made you temporarily deaf? I think two weeks ago was my first actual experience with this.
