Demonstration of total internal refrection (TIR) using a simple laser, a clear tank, water, and a few drops of milk. (It helps to have something to make steam or dust to make the laser beam more visible.) Also includes a demonstration of getting a laser beam to flow through a pouring stream of water, called a "luminous fountain," using a hole in the tank, vinyl tape or duct tape, and a jar or bucket to catch the water.
