Can-Can-on

The .step and .iges files show all the plumbing fittings used, 10' long 3" diameter barrel surrounded by a 6" diameter pressure chamber 8' long, with a piston valve at the rear. 3D printed spacer keeps the 3" schedule 40 pvc barrel centered up in the 6" schedule 40 pvc pressure chamber. At the breech, a 1" pipe connects to a modified sprinkler valve, which dumps the air from behind the piston to suck it backward, allowing all air pressurized to 90psi in the chamber to now slam out through the barrel. A full pop can, placed in the sabot (printed with flexible TPU, like the valve) will be accelerated to roughly 500fps, with more muzzle energy than a 12ga shotgun. I am only posting this for information that is interesting, and I do not recommend anyone build this, because it will launch things farther than you can see, which could be dangerous if not used properly.
