According to Newton's third law of motion, when air is pushed back out of the balloon (out of the end through the opening), there must be an equal and opposite reaction force pushing the balloon forward (the end opposite the opening). When you let a balloon go on its own, it tends to fly randomly around the room, and is nearly impossible to steer. However, when you attach the balloon to a car, you can harness the energy of the balloon to propel the car. The engineering objective in this project will be to design, build and test a car that it is powered by nothing but a balloon. You want to design your car so that it can travel the greatest distance as far as possible.
