Some things are just plain cool! This is one of them. The Dynamo Hand Powered Flashlight Kit contains it’s own generator which is turned by continually squeezing the handle. So you can see what's happening inside, the internal mechanism is contained in the see-through case of the flashlight. Works very well and since it doesn't need batteries, it's actually fairly useful. Includes a spare bulb which is cleverly housed inside the flashlight body.  A gizmo lover's delight! Nicely designed too.
