For a freshman year physics final project, I made a plasma coil bottle launcher. It consists of a trigger-start torch that attaches to a coil of PVC tubing. At the end of the tubing, the bottle sits on a PVC pipe segment. There are notches on the PVC pipe where the neck of the bottle is so that the ignition can propel the bottle attached. To launch a bottle you first have to open the gas canister so that the tubing and bottle are filled with propane. Once this is done, you simply ignite the torch and watch the flame travel through the tube and launch the bottle.
