The Whitney Relay is a set of interconnectable parts that lets students master the art and science of energy transfer in the tradition of the Rube Goldberg Machine or its contemporary Japanese masterpiece: the Pythagoras Switch. Each student receives 5 ramps, 8 marbles, 6 blocks, and assorted parts to construct a chain reaction that could include your whole class. Thoughtful lessons in mechanics, invention and teamwork.
Windmills have captured renewable energy for up to 2000 years. In new forms, wind machines will harness even more power in the future. Construct a classic whirligig to control, measure and apply wind power. With adjustable rotors.
A popular project that teaches game design (beginnings, middles and ends), logic (rewards for difficulty), marble movement (caroms, momentum) and creative design (good games must still attract players.) A rare exploration of the work of play.
Whitney demonstrated the power of machines to guide and ease work. The screws, threads, levers and pulleys of this machine organize effort into power you can feel. Students assemble interchangeable parts and invent a personality for their machine.
