In this instructable I will show you how to make stomp rockets out of house hold materials. I first saw how to make these a while back in a class when we learned about how rockets worked, I did tweak the design a bit, so this isn't quite designed by me. however, these do do a great job of explaining how rockets work and are great for class activities for students young and old.
