"This chemistry demonstration video shows the well known Briggs-Rauscher oscillating reaction. In the video, three solutions are added to a beaker on a stir plate. The solutions contain a variety of reagents, including hydrogen peroxide, potassium iodate, sulfuric acid, malonic acid, and manganese(II) sulfate. After a short time, the mixture begins to oscillate between a yellow and blue color, which continues to cycle for over 10 minutes. The mechanism of this reaction is very complex, involving numerous reactions and intermediates. "
