Purpose: Demonstrate color addition through moving colors.
Description: Snap the red, blue, and green light sticks and attach them to the axle. Dim the lights, turn the crank, and observe a circle of white light!
Assembly instructions:

Unwrap the red, blue, and green light sticks. Arrange the sticks on the bolt so the sticks are resting in the indentations in the positioning plate. Tightly attach the second hexagonal nut. Turn the back of the bolt (on the crank side) clockwise to tighten the front nut. Reposition the light sticks into the indentations if they move. If the assembly does not turn smoothly, with needle-nose pliers, reach behind the large washer and loosen the hexagonal nut (turn counter-clockwise) up to a half-turn. This will allow the assembly to spin as well as further tighten the light stick assembly. Stand the spinner on its base. Turn the crank. If the assembly does not spin smoothly, loosen the hexagonal nut another half-turn. Snap each of the sticks to begin the chemical reaction, and shake the entire assembly to thoroughly mix the chemicals. Hold the base steady with one hand while you turn the crank with the other hand. Viewers should observe a white circle!
