Introduction: How to Make a PVC Rocket Cannon
The above video demonstrates how to fire a rocket under the power of a flammable aerosol. Hairspray or a flammable spray deodorant are the fuels of choice. The total cost of this project assuming the tools needed are already available is about $25. For that price you can make 4 rockets for the launcher, as the foam sleeping pad that they are made of is large enough to make multiples.
