Gee-haw whammy diddle

Some call it a Voodoo stick, others a Bozo-Bozo, Hui-Hui, or Gee-Haw. This is a toy that fascinates children (and adults) of all ages.

This is a stick with a nail and a screw at one end. When rubbed with a wand, the propeller starts spinning and if you're talented then by continuing the rubbing movement you can bring the propeller to a stop and reverse its direction.

Don't worry, there is no black magic behind this seemingly miraculous wand. It's nothing but a little physics - Vibrational Motion. We will spare you the equations that are complicated as this toy is easy.
