Balloon race car runs on air – amazing
Watch your racer speed along using the power of air. Blow up the balloon using the car’s exhaust pipe, let go and watch your balloon racer zoom across the floor!
How does it work ?
When you blow up the balloon, set your racer down, and let it go, escaping air from the balloon rushes out of the straw. This is your car’s propulsion system. The principle at work is Newton’s Third Law of Motion. … The moving balloon powered car is using kinetic energy.
There are different types of energy. They have names like kinetic, potential, sound, light, heat, chemical and nuclear. As the balloon is inflated and stretches, it gains potential (elastic) energy.
