How do glow sticks work?
Glowsticks are made up of three main chemicals:
The Hydrogen peroxide is generally separated by being incased in glass from the Phenyl oxalate ester and fluorescent dye. No reaction will take place so long as these two chemicals remain separated. Glass however is not always used to separate the Hydrogen peroxide.
Have you ever heard of dry ice glow sticks?
Dry ice glow sticks are manufactured in a glowing state with all three chemicals already combined and put on dry ice to stop the chemiluminescence process from occurring. Once the glow sticks are removed from the dry ice and allowed to warm, the chemiluminescence process will take hold and they start to glow.
