Stomp rockets are a great way to introduce flight, pneumatics, and energy transfer through hands-on learning. Paper rockets are very easy to make, and use “virtually free” materials. This will help encourage multiple iterations and exploration of rocket design. You should be able to focus on the important aspects of building and redesigning the rockets. The rockets themselves are very inexpensive, and there are lots of options for their redesign.
I spent a few hours exploring the various supply options at a big box building supply store.
Without knowing exactly what I would end up with, I brought a good collection of supplies to a local space to work it out. In the video above, you can see some of what worked, and a few things that might be good to avoid in building your own stomp rocket launcher.
