Builder Lab™ — Motion Machines (Balloon Powered Car Lab) (STEM.DELUX)

Engineers don't just build things. They build, test, and improve. This kit puts your child in that cycle.

Your child will construct a car powered entirely by air escaping a balloon — then figure out how to make it go faster, farther, and straighter. It's Newton's Third Law in action, and they won't even realize they're learning physics. The kit includes a balloon, straw nozzle, wheels, axles, and a complete lab guide with build instructions, challenge extensions for ages 5–13, and a data-tracking prompt. One build leads to ten experiments.

What they'll discover: How air pressure creates motion — and how one small design change can double the distance.
