Change kinetic energy into electrical energy by cranking this hand-held 'dynamo!' Clearly demonstrate how electrical energy can be produced by moving an electrical conductor through a magnetic field, a discovery made by Michael Faraday in 1831. This cool tool has a battery that can provide light for many hours, demonstrating the efficiency of LED technology.
Keep one in your car, next to your bed, or in your tool box, and you will always have light when you need it!
