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.
-2 liter soda bottle
-1in wide bike tube( at least 3 ft long)
-1in wide pvc, abs pipe (at least a foot long)
-pen or pencil
Step 1: The Launching System
To make the launching system stretch the bike tube over the 2 liter soda bottle and add some tape if it doesnt seal well enough, then attach the other end of the bike tube to the pvc pipe and add tape if needed, now the launching system is done, so now we need to make a rocket.
