Light Behavior with Gummy Bears and Lasers

Claudia demonstrates light absorption using gummy bears, gummy worms, and lasers. The video covers safety measures for handling lasers and shows how different colors of light pass through or are absorbed by objects of the same or different colors. The experiment illustrates that objects appear in the color of the light they do not absorb. The video concludes with a demonstration of light absorption using human skin, explaining why red light passes through while other colors are absorbed.

• Do not look at the laser beam.

• Do not point the laser beam at anybody.

• Do not use the laser in a dark room.
