I've posted this demo on the site before, but now I have it in high definition. It's a classic experiment showing the principle of inertia in action. Watch the video!

When studying light, students need to learn that visible light can be refracted into its different wavelengths. Of course it's ROYGBIV (red, orange, yellow, green, blue, indigo, and violet). A simple prism is usually used to do this, but I think there is a better way. Fill up a fish tank with water, put it in the sun, use a mirror and ta da a spectrum! Check out the video.
