This is truly a colorful chemistry experiment.  You will need glucose, sodium hydroxide, methylene blue and a conical flask. Put some glucose in the flask and then add a few crystals of sodium hydroxide. Then add some water and shake the solution vigorously so that the contents mix properly. To this solution add a few drops of methylene blue. The solution will become sky blue in color. On shaking the mixture becomes dark blue. But if the flask is kept still then surprisingly after a while the mixture becomes colorless. This is because the mixture has consumed all its oxygen – which renders it colorless. On shaking it absorbs more oxygen from the air and regains its blue color. On remaining still it consumes the oxygen and becomes colorless.
