Demonstration experiments in secondary stage
The blue bottle experiment (C2.2.2.2) is a favourite demonstration experiment in practical lectures. In the classic version, the experimenter shakes a bottle filled with a clear liquid which then turns blue. After a while the liquid becomes colourless, but then turns blue again through shaking.
