Things that Really Glow under a Black Light

I recently wrote up a list of Materials That Glow Under Black Light. Since that time, I've experimented with a black light myself. What did I learn? For one, I've confirmed that the materials in my list do glow. A notable exception was my fluorite (apparently the fluorite has to contain a particular impurity to glow). However, if want you to look at something really cool, check out a Lego that has fluorescent parts (such as this Bionicle, Turahk). These toys glow like a lightbulb and keep on glowing for a couple of seconds after the light is turned off. Other notable glowers: pipecleaners (chenille craft sticks) and weedeater twine. You get lightsaber action with those two materials! Many plastics glowed brightly and over a broad color range. The cheap little plastic balls used for cat toys were so neat I think the cat will never see them again. Do you have glowing items to add to my list? If so, please e-mail me and I'll check it out.
