The history of glow sticks is over 40 years old when Edwin Chandross, a chemist at Bell Labs, invented the glow technology which used chemical energy to emit light. This was quite an achievement as at that point either battery or electrical power was used as an energy source for emission of light.

Many scientists took Chandross' work and refined the process further. Unfortunately for Chandross, the patent for Chemical Light Device was registered by Richard Taylor Van Zandt in the US Patents office.

Glow sticks can be used just once and come in different sizes in translucent plastic tubes. The chemicals contained within are glow stick are isolated in a brittle inner case, which when broken allows the chemicals to combine and produce light through a chemical reaction known as chemoluminescence.

Today, glow sticks are used the world over as a source of light and millions of people all over the world use these colorful sticks. It is believed that nearly 15 million glow sticks are used by the United States Department of Defense each year.
