We went to the Atlantis space shuttle replica, post here, and afterwards we ( Little Man, Grandma and myself ) stopped by Hobby Lobby and saw this and thought it would be fun 🙂 Here is a link to purchase this rocket.
This is a very simple experiment that you can do over and over again. Small amount of vinegar goes into the clear tube and you pack baking soda into the bottom of the rocket. Then set the rocket on top of the tube. The chemical reaction creates a gas and pressure which shoots the micro rocket about 6 inches up.
