Black lights are lights that emit ultraviolet radiation. Since you can't see ultraviolet light, the lights can be invisible or "black" to your eyes. Many materials that absort black light re-release less energetic light in the visible spectrum, causing them to glow. This video looks at common materials that glow in the dark under black lights.
