Glow sticks first came on the scene in the early seventies and gained almost instant popularity with campers and divers. In fact they were actually developed by the US Navy for use in underwater diving missions, especially at night. You see, divers needed a lighter and more reliable way to see underwater than waterproof flashlights that would often run out of juice at inopportune times.
What exactly is a glow stick? Well, it is really nothing more than a plastic stick that contains certain substances that produce light thorough a chemical reaction. These items can be used by just about anyone, since they are non-toxic and they do not produce any heat. Millions of them are sold each year all over the world.
