The STEM Lab hand crank flashlight is a useful human-powered tool! Kids 8-12 can assemble this toy in around 30 minutes with the full-color guide included. They will build a gear box that connects the handle of the flashlight to a power-generating motor. When they crank, their motion is translated to power through an electromagnetic coil (cool, huh!?) and turns on a bright white LED!
