Rocket Balloon project by Hobbyscience
What you need:
Drinking straw, tape, string, long balloon.
What you do:
Fasten the string across a room threading the string
through the straw. Inflate the balloon and holding firmly
to the valve, tape the balloon to the straw.
Release the balloon and watch it move along the string.
This one is fun and if you set up more than one string
track you can have races!
