Balloon Rocket

Lilly, Braeden and I did Balloon Rocket for our Science fair. A Balloon Rocket has balloon taped to a straw and the straw is slipped onto the string. You let go of the balloon and watch it zoom along the string.  We discovered that the type of balloon's affect how far and fast it goes.  Our group worked very well and were sensible.
Check out our imovie of our experiment.
