Liquid Light Pipe

Return to Geometrical Optics

Description:

A laser is positioned so its beam is pointing at a small hole in the side of a plastic container. When the stopper to the hole is removed and the water pours out in an arc, the laser light follows the path of the water. NOTE: use a few drops of milk or just a very small amount of milk powder of coffee creamer powder in the water to make the beam show up.

Location:

• Laser: Shelf M-2
