None ... The Glow-worm is a tiny, wormy dragon that lives in caves and other darkened areas. They are utilized at night as a light source by Vikings. Glow-worms are classified as Cave Dragons in the Complete Book of Dragons, but as mentioned as being Nanodragons in How to Train Your Viking. This dragon's name has been spelled in two ways in the Books: Glow-worm and Glowworm.
To make a glow-in-the-dark toy, what you want is a phosphor that is energized by normal light and that has a very long persistence. Two phosphors that have these properties are Zinc Sulfide and Strontium Aluminate. Strontium Aluminate is newer -- it's what you see in the super glow-in-the-dark toys. It has a much longer persistence than Zinc Sulfide does. The phosphor is mixed into a plastic and molded to make most glow-in-the-dark stuff.
