just something me and my friend made we made it in my friends basement using the materials listed. The tools we use were a saw to shorten the pipe itself, and a drill for "smoke holes if you will." there was a lot of trial and error like how to make the missile fire accurately we fixed this by adding a nose cone but adding fins was the biggest problem that we still haven't solved because the rocket fits so snugly in the pipe. Another thing that we added on after our first trial was to add the shield in the front to prevent the user from being hit by the back blast of the rocket. If we were to try this again we would probably make the pvc pipe wider so we could fit the fins inside the pipe.
