For the small wheels you could also try using a section of a balloon. The trap will snap forward, propelling your car. What's happening? The above procedure used rubber bands to provide traction; can you think of a better way?

DISCUSSION: The rocket car is propelled along the floor according to the principle stated in Isaac Newton's third law of motion. "For every action there is an opposite and equal reaction." The balloon pushes on the air and the DESCRIPTION: A small car is propelled by the action/reaction force generated by a balloon.

Have students share ideas and help them get to the idea that the air is being forced out of the balloon (action) and in turn the balloon is propelled forward (reaction). Draw on the board How could placing a bumper on the front of this car affect the law of the conservation of momentum between these cars? Procedure:

For example, student groups seek to develop the best balloon-propelled car by testing a number of variables, including the aperture of the straw through which air escapes from the balloon. The "best" width is the width that allows the most air to be released - up to a point.
