What makes glow sticks “glow?
The light is produced when two solutions are allowed to mix, causing a chemical reacton. One of the solutions is kept in a thin tube of glass which, when the tube is bent or flexed, allows the mixture to take place. In order to initiate the glowing reaction, squeeze the shape until all the inner tubes have been broken, then shake vigorously while keeping the front face down.
Glow Sticks glow because of two chemicals and a dye in a glass vial within the glow stick. To activate the stick you must break it. Inside a glass vial within the stick is a mixture of dye, diphenyl oxalate and hydrogen peroxide. Mixing these two chemicals causes a reaction that releases energy that activates the dye. The color of the emitted light depends upon the structure of the dye.You can find more information here: http://en.wikipedia.org/wiki/Glow_stick#…
