You just cracked your favorite glow light or glow necklace when it dawns on you–how on earth do these things really work? Light sticks and other glow items generate light when two chemical compounds are mixed together in a process called chemiluminescense. This process converts energy directly to light without heat, flame or spark. To keep the reaction from occurring prematurely, the two compounds are kept separate by storing one in a very thin capsule, which is broken by flexing or bending the product tube.
