Educational Hand-Powered Flashlight Kit

This Dynamo Hand-Powered Flashlight comes as a kit at your assemble. Apparently it takes about 30 minutes to put together, and is intended to teach kids the principles of electrical generation. It also has a translucent casing that was designed so children could see how squeezing the handle spins a magnetic disc between two coils of copper wire, creating and transferring an electrical current to a light bulb. It's being sold for $12.95. We featured a similar Dynamo Flashlight previously. :: Dynamo Hand-Powered Flashlight via Unplugged Living
