The Whitney Relay is our system of interchangeable marble tracks: each one triggers the other. Construct an all new rubberband-powered tractor that can add push, pull, lift or tip to your inventions. With all the parts for beginners and new parts to upgrade earlier sets (once known as Pythagoras Switch). Video your work.
