Glow in the Dark Paint

Glowing, glowing, . . ., gone?

Light comes in all shapes and sizes, and we use it in many different ways. One set of types, luminsecent, comes without extra heat and shows up in some of the strangest places! We have it in glow sticks, from black lights, even from some Lifesavers candies. What is it really about?

And how do those neat glow-in-the-dark things work?
