This might be a silly question, but what are people using glow sticks for? What is the intended use or reason for packing them, and what do they actually get used for? I see them listed often in FAKs, but I don't understand why. After a little research I see that they can be used to mark patients in a triage situation, but that can't be all. My imagination is weak this morning, so I need to hear what other folks are doing with them before I bother to procure any.
