Belousov-Zhabotinsky Oscillating Reactions

Above is a video showing a Belousov-Zhabotinsky oscillating reaction. An oscillating reaction occurs when parts of the solution periodically change, this leads to the solution not being in equilibrium thermodynamically, which is not normally what is expected. My chemistry knowledge is pretty sketchy so take my explanation with a grain of salt. Follow the previous link for a better explanation.

Below is a video which shows a fellow going through the steps of creating a Belousov-Zhabotinsky oscillating reaction. It also sheds light on what it is all about.
