Description:

This activity demonstrates the additive properties of light. Different-colored lights are shown on the same spot on a screen so that the reflecting light is white. Colored shadows, however, can be made by holding an object between the light sources and the screen. The site provides an explanation for how this occurs along with extension activities and information about the eye’s retina. Materials needed and assembly instructions are also included. This activity is part of Exploratorium's Science Snacks series.
