They light up because of chemoluminescence. Basically, there's a chemical reaction going on, and one of the products of that reaction is energy in the form of light.
Glow sticks are a chemical light.
The warmer conditions the glow stick is in the brighter it will light up but for a short amount of time . However, on low temperature conditions the glow stick will light up for a longer time period but it will not light up as bright
Glow sticks do not "capture" light. The light is produced by a chemical reaction. See the related link for a more in-depth discussion.
Light Energy, Potential Energy, and possibly Heat Energy.
They glow so you can see in the dark and so they look cool!
Glow sticks are a chemical light.
Glow sticks will show up better if you put them in the dark instead of leaving them in the light. Glow sticks are activated by breaking the tube inside and shaking them.
Glow sticks are exothermic.Exothermic is when heat/energy is released. And that is exactly what glow sticks do. but the energy being released is in the form of light.

no acid is in glow sticks. Glow sticks usually have two chemicals that react with each other to create chemiluminescence, by giving off energy in the form of light
Try Glow sticks.
Apparently if you put them in the freezer they will last longer and you can reuse them. tried it once it did light up again but not very brightly.

Glow sticks are used for many purposes and are widely used by military forces as a light source and light markers. They are made of waterproof materials which are less expensive.
Glow sticks aren't just for raves, nor are they just for kids on Halloween. Glow sticks can be a great safety asset when outside in any dark or dangerous condition. Many athletes use glow sticks to light their paths when running and to make them more visible to cars. Glow sticks can also be useful for roadside emergencies, for power outages, or in substitute of a flashlight. Glow sticks are inexpensive and can be purchased at most party stores and sports stores.
