oscillating reaction

A chemical clock is a complex mixture of reacting chemical compounds in which the concentration of one or more components exhibits periodic changes, or where sudden property changes occur after a predictable induction time.[1] They are a class of reactions that serve as an example of non-equilibrium thermodynamics, resulting in the establishment of a nonlinear oscillator. The reactions are theoretically important in that they show that chemical reactions do not have to be dominated by equilibrium thermodynamic behavior.

I recently stumbled upon this absolutely dazzling chemistry experiment, and I just had to share it. What you will see is a pretty rare reaction in chemistry – an oscillation reaction. Three clear solutions are combined, and the color gradually changes to amber. Suddenly, the whole thing goes dark blue! Then it stays blue, reverts [...]
