** ABSTRACT **
====The purpose of this study was to determine how much light glow sticks gave off after being under different conditions, like being soaked in hot or cold water. Glow sticks are made out of Phenyl Oxalate and Fluorescent Dye Solution, with plastic casing on the outside, and a glass chamber in the center, filled with Hydrogen Peroxide Solution, when the glass chamber is cracked the Phenyl Oxalate, Fluorescent Dye Solution, and the Hydrogen Peroxide Solution mix, causing the glow stick to glow. Different colored glow sticks were cracked, and then measured with a vernier light sensor, to determine how much light the glow sticks gave off. It was determined that green glow sticks gave off more light than any other color glow stick. Green glow sticks have more solutions in them than the other colored glow sticks, so when the solutions mix, they give off more light than other glow sticks.====

====An improvement to this experiment would be to put the glow sticks in the freezer before they are cracked. This way, they will give off more light. The amount of light the glow sticks give off would be measured by a vernier light sensor, to determine how much light the glow stick gives off in lux, this would affect the outcome. It would be interesting to determine if orange glow sticks gave off more light than pink glow sticks after being soaked in water for 10 min.====
