The ‘Blue Bottle’ Experiment

In this classic demonstration, from the Royal Society of Chemistry, a colourless solution of potassium hydroxide, glucose, methylene blue, and ethanol is poured out into a sealed clear bottle. When shaken, air dissolves and the solution turns blue. Other indicators can be used to produce other colours.
