Shake Light - Magnetic Induction Flashlight - No batteries Need

Instead this flash light is powered by magnetic induction, as described in Faraday's Law. A magnet is surrounded by copper coil which induces voltage in the coil when it is shaken. Instead of a traditional light bulb this flash light makes use of a super bright and durable LED. Shaking for 30 seconds provides up to five minutes of light!This may be the last flashlight you ever own.
