Editing Shaking Solution (section)

===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.

Remember: There is air all around us, including inside of the flask, and part of that air is oxygen. So when the flask is shaken, some of that oxygen will dissolve into the solution. The oxygen will oxidize the indicator, and removes some of the electrons. This is what makes it change colors! Then, the glucose in the solution will reduce the indicator, and give it some electrons. This is what makes it turn back. Since there is so much glucose in the solution and very little indicator, this can happen a lot, and can be repeated for several hours!
