Is a glow stick a chemical change?
The outer tube is filled with dye, which determines the color of the glow stick, and a chemical called diphenyl oxalate. When you crack a glow stick, you break the glass inside. Its ingredients are then free to mix and react, releasing carbon dioxide and chemical energy, which is converted to visible light.
Do glow sticks have poison in them?
The exact chemicals inside a glow stick may differ based on the color of light emitted. Toxicity: Ingestion of a mouthful of the liquid from a glow stick is considered to be minimally toxic, causing only minor mouth or throat irritation. The liquid may also cause minor skin redness or irritation.
Do glow sticks expire?
The glow sticks should be stored in a cool, dry place. Foil wrapped glow sticks (for example 6” light sticks and 1.5” mini sticks) will last 2 to 4 years. Glow sticks will work past these expiration times but their brightness and duration will be greatly reduced.
