This blending creates the illusion that they're actually white! How does that happen? Light and the color white are all of the colors of the rainbow in one.

Where do you think the colors went? Did a leprechaun catch the rainbow? The rapid spinning of the disappearing color wheel causes the colors to “blend” into each other. Wind the string by moving the wheel in a motion similar to a jump rope.įinally: Pull the string tight to get the wheel spinning. Feed the string through both holes and tie the ends together. Next: Poke two small holes through the wheel, near the center of the circle. Glue the colorful circle on the cardboard with the colored side out. Third: Use the cup to trace another circle on the cardboard. Color each section a different color using the 6 sharpies.

Second: Use a ruler and pencil to divide the circle into 6 even sections. Then on the big circle piece of plate, trace the mouth of the cup with a pencil. Sharpies (red, orange, yellow, green, blue, and purple)įirst: Use the scissors to cut the edge off of the paper plate.
