A glow stick is a single-use translucent plastic tube containing isolated substances which, when combined, make light through a chemical reaction-induced chemiluminescence, and which does not require an electrical power source. Glow sticks have been seen used by the Atlantis expedition to light up dark areas. They were also used as identifiers when in deep fog. (SGA: "The Brotherhood", "Whispers")
