WHAT IS HAPPENING HERE?
WHY THE COLOUR CHANGE? IT"S CHEMISTRY! If you vigorously shake the bottle it turns blue. Left for a while it returns to a colourless solution. The reason this happens is that the oxygen combines with the Methylene Blue causing a reversible colour change. This colour change is due to a set of reversable chemical reactions, known as REDOX reactions. See Magic Bottle II for more details. FIND OUT MORE:-
