This is a video tutorial on how to make a simple bottle rocket. This is an actual bottle rocket, made from a 2-liter soda pop bottle. You'll also need some PVC pipe and cork.
Here are some tips for improving your rockets flight: Make sure the cork is nice and tight (not too tight as it might go Kaboom). Make sure the launch platform isn't too tight on it, and don't fire it at your eye! Enjoy.
