The boys tried a second experiment. they built a balloon car like the one seen here. as the gas in the balloon is released, the car moves. ben and dylan discovered that the bigger they blew up the balloon, the farther the car moved. this balloon car is a good model of newton's:

newton's third law of motion

Explanation:

The model of balloon car is example of newton's third law of motion which says that to every action there is always and equal and opposite reaction. As the balloon is inflated and then release the nozzle, the rubber contacts and pushes the air forward out of the nozzle, the air pushes back on the rubber and propelling the balloon forward.
