Write down instructions for someone who is using air balloon car for the first time.
To use the air balloon car: 1) Make sure the balloon is securely attached to the straw with a rubber band. 2) Blow into the open end of the straw to inflate the balloon. 3) Pinch or press your finger over the straw opening to keep the air inside the balloon. 4) Place the car on a smooth, flat surface. 5) Release your finger from the straw opening. 6) Watch the car move forward as the air rushes out of the balloon through the straw, creating thrust. The escaping air pushes the car in the opposite direction.
Explanation
The chapter explains that the air balloon car uses a plastic bottle body with chopstick axles and bottle cap wheels. The balloon attached to a straw provides propulsion through air pressure. When air escapes from the balloon, it creates a forward thrust that moves the car, demonstrating Newton's third law of motion.
