Explore the first, and best, way of generating electricity! Falling water has been turning potential into kinetic energy since time immermorial. Our simple demo allows you to exlore hydroelectric power right in your classroom. Using water from a faucet, you spin a small wheel that in turn drives a generator, which can produce up to 6 V DC. The turbine is made of plastic and brass and is resistant to water damage. Includes: all tubing, plastic and brass construction, small color wheel (turns white when turbine reaches optimal speed) and instructions.
