Have you ever wondering how a glow stick works? Have your students asked this question? Glow sticks function because of a chemical reaction and some great engineering. That’s right! Someone had to design a way for glow sticks to keep the chemical reactants within them separate until they are ready for the chemical reaction to occur.

A glow stick 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. If you are interested in chemical reactions you should visit this post on Forming a Precipitate.
