Bending Light

This Bending Light activity & project also includes:

Astound your aspiring physicists with a simple demonstration of refraction. They watch as you allow a stream of water to spray out of a hole in an aluminum can. Then, as you shine a light down from the top opening, its path follows and bends with the stream of water. Though this is titled as "Home Demo No. 39," you might choose to do it in class rather than rely on students to track down soda cans and flahslights at home.
