How to Perform the Rocket Balloon Experiment

My name is James Lincoln. I'm a physics teacher here for About.com. Today we'll be performing the rocket balloon experiment. And here are the materials that you'll need: The rocket balloon experiment is a simple demonstration of Newton's Third Law. The way you do it is get a long tubular balloon like you might use for balloon animals and fill it with air and let it go. As the balloon pushed the air out, an equal and opposite force will push the balloon forward and it will go off like a rocket. You can enhance the experiment by taping a straw to the top of the balloon and threading a string through the straw. This will allow you to guide the balloon in the path that you choose. As the balloon pushes the air out, the air pushes the balloon forward with an equal and opposite force. And that's how real rockets work. But it's much safer to use a balloon than one of those dangerous rockets that might explode. You may also want some styrofoam cups to make little fins for the rocket balloon.
