We made the balloon powered car, with slight (aesthetic) modifications. It works beautifully, and we had a great discussion about Newton’s third law of motion. The whole project, including gathering materials, took about 20 minutes, but my son has had hours of fun (oh, yes, and learning!) with his creation. Very nice. Thank you!
