Glow sticks are plastic tubes containing chemical substances that are isolated and that produce light due to a chemical reaction. There are several patents for glow sticks and the earliest ones dates back to June 1965 which lists Eugene Daniel Guth and Bernard Dubrow as inventors of glow stick.
However the chemical substance that induces chemiluminescence in a glow stick was invented by a group of scientists based on the works of Edwin Chandross. Edwin Chandross was a chemist at the Bell Labs who used chemical energy to emit light.
These glow sticks are available in various shapes and sizes in plastic tubes that are translucent. There is a brittle inner case which contains chemicals and is surrounded by another chemical and these chemicals when they come in contact react and produce light through a reaction known as chemiluminescence.
These glow sticks are used globally for producing light in vast applications. The United States Department of Defense used these lights for military purposes. Glow lights are also used at festivals and also during natural disasters such as earthquakes, hurricanes or tornados.
The chemical contained in the glow sticks are non-flammable and non-toxic. The glow sticks usually contains ingredients such as fluorescent dye, cyalume-phenyle oxalate ester and hydrogen peroxide. The glow sticks are also known as neon sticks, glow lites, party sticks and neon glowsticks. These glow sticks can withstand high underwater pressure and thus they are used as lures to catch fishes too.
