A glow stick is a single-use, translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence, so does not require an electrical power source. Glow sticks are often used for recreation, but may also be relied upon for light during military, police, fire, or EMS operations.

Famous quotes containing the words glow and/or stick:
“I dont think there is anything on earth more wonderful than those wistful incomplete friendships one makes now and then in an hour’s talk. You never see the people again, but the lingering sense of their presence in the world is like the glow of an unseen city at night—makes you feel the teemingness of it all.”
—John Dos Passos (1896–1970)
“If a madman were to come into this room with a stick in his hand, no doubt we should pity the state of his mind; but our primary consideration would be to take care of ourselves. We should knock him down first, and pity him afterwards.”
—Samuel Johnson (1709–1784)
