Hand-Crank Generator

The Hand-Crank Generator is a great tool for learning the difference between an incandescent light bulb and a light-emitting diode (LED). Use your cranking power to discover how much energy it takes to light up two different light bulbs. As you crank, a generator transforms your muscle power into electrical energy.

This kit includes:

  • Hand Crank
  • LED Light Bulb (2)
  • Incandescent Light Bulb (2)
  • Plastic Protective Cylinder (2)
  • CFLs and Mercury – What you need to know Flyer
