Explore alternative energy by designing a car propelled by a rubber band and a propeller.
Each kit includes:  wheels,  axles, straw, propeller, wood, screw eye, washer and a rubber band.
Wood is NOT precut - it will need to be shaped, cut and sanded. We encourage the students to work with hand tools to fabricate their own design.
