6F10.25 - Color Wheels

See paragraph one in the procedure section.
See paragraph two in the procedure section.
Code Number:
6F10.25
Demo Title:
Color Wheels
Condition:
Excellent
Principle:
Colors and Spectrum
Area of Study:
Optics
Equipment:
Color Wheels, DC Motors, Power Supplies, light sticks -- red, blue, and green.
Procedure:

The color wheels may be hooked to a variety of our DC motors using the proper shaft adapters available. The motor used depends on your particular desires. As the speed of the motor is increased the wheel should traverse the colors of the spectrum until you reach a speed where the disk is a creamy white. 

Attach the light sticks to the wheel with some plastic straps.  Snap the light sticks so that they start to glow.  Rotate the wheel and see a nice bright white color produced.  The light sticks will last up to two hours.
