I just want to say, I am getting my name changed.... Hopefully. So don't flame about my name please. But I wanted to know how this worked and what parts I would need, apart from the aluminium frame, Nerf football and CO2. (The picture is this: http://i188.photobucket.com/albums/z...NerfMortar.gif
). And if anyone knows how to build it it would be greatly appreciated if you tell me and the rest of the people interested in this.
