Rubber Band Powered Propeller Engines Make a propeller yacht and a racer, both powered by a simple rubber-band engine. Forget batteries, and learn how the useful material, rubber, can store energy and release it to generate enough wind power to really MOVE these machines. You'll be surprised by the amount of wind energy created by the spinning propellers to drive the racer on land, and the yacht on water. Perfect for budding engineers to learn about energy transformations and how simple machines work.
