Whether used for safety, night diving, night sports, concerts, parties or special events, glow sticks provide convenient sources of light without the use of electricity or heat. The glow stick, sometimes called a light stick, contains a thin glass tube suspended in hydrogen peroxide and filled with phenyl oxalate and fluorescent dye. When the stick is bent, the glass tube breaks, and the substances mix, causing a light-emitting chemical reaction. Glow sticks last about 5 to 12 hours, or longer, depending on the product. However, you can make glow sticks light up again with the use of heat.

How to Make Glow Sticks Light Up Again
Fill a pot with water and heat the water to just under boiling. It is not necessary for the water to simmer. Ideally, the water should be scalding hot.
Place the used glow sticks in the water. Leave them in for 30 seconds to 1 minute. The glow stick should begin to glow increasingly as the chemicals inside react to the heat.
Use tongs to remove the light sticks from the pot of water. Allow the sticks to cool so they can be comfortably held.
Use the glow sticks promptly, as they will lose their glow rapidly. The luminescence will last about 30 minutes to 1 hour.
