[PDF] factors that affect brightness of a glow stick

How does temperature affect a glow stick?

In the case of glow sticks, this means a hotter temperature will make the glow stick glow more brightly. However, a faster reaction means it reaches completion more quickly, so placing a glow stick in a hot environment will shorten how long it lasts. On the other hand, you can slow down the rate of a chemical reaction by lowering the temperature.

Why does a light stick stop glowing after a chemical reaction?

This is because the chemicals were used up in the chemical reaction. When the chemical reaction inside a light stick ends, it stops glowing. If you observed the light sticks over a few hours, after a while the light stick in the hot water becomes dimmer than the light stick in the cold water.

How does a glowstick work?

After the glass capsule is broken and the solutions mix, the glowstick glows. A glow stick, also known as a light stick, chem light, light wand, light rod, and rave light, is a self-contained, short-term light-source. It consists of a translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence.

What causes orange light from a glow stick?

This plot thus shows that the orange light from an orange glow stick (identical to the one in the above glow stick disassembly image) is created by a greenish-yellow light emitting chemoluminescent liquid partially inducing fluorescence in (and being filtered by) an orange plastic container.
