Overview

Students design and build a car powered entirely by a balloon, no batteries, no motors. They predict how it will move, build the body, axles, and wheels from cardboard and straws, then test and improve their design. Along the way, they discover how escaping air pushes the car forward, a hands-on lesson in forces and motion.
