===Short Explanation===
This demonstration works because it is a ''Redox Reaction''. Redox stands for Reduction/Oxidation, which are reactions that happen due to an exchange of electrons. ''Reduction'' is when a molecule gains electrons, and ''Oxidation'' is when a molecule loses electrons. A helpful way to remember this is with this phrase: "'''LEO''' says '''GER'''". The letters in '''LEO''' stand for '''L'''oss '''E'''quals '''O'''xidation, and '''GER''' stands for '''G'''ain '''E'''quals '''R'''eduction.

When the Potassium Permanganate (KMnO<sub>4</sub>) is added into the solution, it is reduced (receives an extra electron) and changes from a purple color to a green color. As this happens, there is a middle period where the colors mix and make the solution look blue. The reduced state then goes through a second slow reduction, which causes a reaction with the water and makes manganese dioxide, a brown-yellow solid, precipitate. In a weak solution, the brown color isn't as apparent, so it will look like it turns yellow! When more of the KMnO<sub>4</sub> is added into the solution and goes through further reductions, the brown color will start to become more prominent, and will make the end solution look like a rusty red instead of yellow.
