How To: Make a Hairspray-Fueled PVC Rocket Cannon

This week, I've been working on a project that sort of takes a spin off an old-style potato gun. Using PVC pipe and the rapid combustion of hairspray, we can launch a rocket hundreds of feet into the sky. As usual for my projects, I tried to use only materials and parts that are commonly available. I even give two different forms of ignition, in case one method ends up being hard to come by.
