Sky Writer Wand

The Sky Writer wand has a row of flashing LED's, wave it in the air and suddenly you will see images appear in thin air. Utilizing persistence of vision the Sky Writer Wand uses a micro controller chip to generate patterns sent directly to the LEDs. When waved through the air each section of the image is formed sequentially and your eye will see the full image due to persistence of vision. Fun to mount on bicycle wheels or other spinning objects for a unique visual display. Great for science projects, or as non flammable "fireworks" . Options are given in the instructions for alternate color patterns and other expansions on the basic idea.
