What is a Lightstick and How Does it Operate? Lightsticks or glowsticks are used by trick-or-treaters, divers, campers, and for decoration and fun! A lightstick is a plastic tube with a glass vial inside of it. In order to activate a lightstick, you bend the plastic stick, which breaks the glass vial. This allows the chemicals that were inside the glass to mix with the chemicals in the plastic tube. Once these substances contact each other, a reaction starts taking place. The reaction releases light, causing the stick to glow! The chemical reaction in a lightstick releases energy in the form of light. The light produced by this chemical reaction is called chemiluminescence. Although the light-producing reaction is not caused by heat and may not produce heat, the rate at which it occurs is affected by temperature. If you place a lightstick in a cold environment (like a freezer), then the chemical reaction will slow down. Less light will be released while the lightstick is cold, but the stick will last much longer. On the other hand, if you immerse a lightstick in hot water, the chemical reaction will speed up. The stick will glow much more brightly, but will wear out faster too. http://chemistry.about.com/od/howthingsworkfaqs/a/howlightsticks.htm
