one Air pump and two cars with one packet of balloon
Learning through Playing is Fun: Theoretically, the cars should go further and faster as you can blow up the balloons, but the air resistance will also become greater. Don’t worry, the kids will figure out the best size of the balloon and make the car run further after continuous trials, and learn more about Aerodynamics at the same time.
