Plastic tubes filled with some kind of chemical. There is a smaller glass tube inside the plastic tube filled with another chemical. When you flex the plastic tube, and break the glass one, the two chemicals react and put out light. You can get them in various colors, red, orange, green, blue and possibly others. Commercial fisherman use the green ones at night, they're often included in "survival kits" or road emergency kits. They're popular with ravers, who move them around to make light trails as they dance.
I've seen them in the camping section of hardware stores for over $5!. You can get them at rave/club supply places much cheaper than that. $.80 each, in packages of 50 at http://glowstickfactory.com/6_inch_glowsticks.asp I'm sure you can find other places with a websearch.
