Physics
Discover how light, color, and energy are all related in this simple experiment using only gummy bears and laser pointers. All wavelengths of light have different energy and are absorbed or reflected by materials based on that energy. Depending on the wavelengths of light absorbed and reflected by an object we perceive its color. Watch this idea in action (literally!) inside of gummy bears.
