Briggs-Rauscher Oscillating Reaction

This is really impressive experience captured on video.

This is the Briggs-Rauscher Oscillating color change Reaction.

“The Briggs-Rauscher reaction, also known as ‘the oscillating clock’, is one of the most common demonstrations of a chemical oscillator reaction. The reaction begins when three colorless solutions are mixed together. The color of the resulting mixture will oscillate between clear, amber, and deep blue for about 3-5 minutes. The solution ends up as a blue-black mixture.”
