Well I didn't think it could be done, but I built a gun even more useless than the horseshoe launcher.
I built it a few months ago, October I believe. It's a chamber sealing coaxial that shoots toilet paper. I haven't and probably never will TP someones house, and even if I did I wouldn't use the gun. I built it because I was frustrated with my main project and this gun is the simplest of any of my ideas. I build guns to design and build them more than to shoot them anyway. I was going to paint it flat black and have a nice cover for the rear of the gun, but I was dissapointed with the performance so I didn't bother.
It shoots about as high as someone with a good arm could throw, and is louder than I thought it would be.
I'll get some pics up of the insides once I can find my memory stick, but here is a short video. I wasn't aiming for the trees but the second shot lands right on the top...ugh
