Balloon Car Experiment, The Beech Classroom(6th class)
The science behind the balloon-powered car is very simple. In the same way a balloon would usually travel a fair distance when the air is released, the same applies here. In this case, the car is being pushed-along by the compressed air releasing from the balloon. This is the energy of motion, called kinetic energy. The air being stored in the balloon is an energy source for the car and is turned into kinetic energy when released.
