These working flashlights shine a bright light with just the squeeze of the handle. These unique flashlights are actually electrical generators that use a magnetic field (and your kinetic motion) to create an electrical current. In 1831, Michael Faraday discovered how to transform mechanical energy into electrical energy using a device similar to these flashlights. Demonstrates the transformation of mechanical energy into electrical energy. Color may vary.
