Glow stick glow time: The glow time of light sticks varies from 4 to 48 hours. The length of time the light stick emits light is inversely proportional to the ambient temperature (i.e., the higher the temperature, the shorter the glow time). It is also inversely proportional to the initial brightness of the light stick (i.e., the brighter the initial light, the shorter the glow time). Based on these characteristics, we can place a used glow stick in a low-temperature environment (such as a refrigerator or freezer) to suppress the chemical reaction of the two liquids inside and use it later.

Light stick shipping and saving: During transportation and storage, light sticks should avoid exposure to high temperatures and any impact or falling. This is to prevent affecting the glow time and brightness of the light sticks, as well as to avoid breaking the glass tube inside, which would cause the glow stick to emit light prematurely and become unusable.

Glow sticks are made by folding plastic tubes around glass tubes. When broken, liquid A inside the thin glass tube flows out and rapidly mixes with liquid B inside the plastic tube, triggering a chemical reaction. The energy released from this reaction is transferred to fluorescent pigment molecules, which then release energy in the form of visible light (transitioning from a higher energy state to a more stable lower energy state), converting chemical energy into light energy. Liquid A consists of different colored fluorescent pigments and bis oxalate diester (CPPO) dissolved in a solvent. Liquid B is a solution of hydrogen peroxide dissolved in a solvent, with the main solvent being an ester compound.
