Fun Fly Stick - Cool Science Toy

What is a Fun Fly Stick? Simply a portable Van de Graaff generator. A moving rubber belt inside the wand generates an electrostatic field that balances the gravitational force on light conductive objects. This means the objects will levitate! And it is COMPLETELY safe! No shocks or zaps! more gadget novelty gift,visit:http://chinagift.en.ecplaza.
