Cosi Columbus: Coffee Filter Rainbows
Science experiment that demonstrates chromotography. Includes full list of materials, procedures, and scientific explanation of what happens with different colors when they are soaked with water.
Exploratorium
Exploratorium: Science Snacks: Rotating Light
An experiment where polarized light is shone into a solution of sugared water, causing each of the colors in white light to change direction in varying amounts.
