The Belousov-Zhabotinskii reaction (or BZ reaction)

More Design inspiration the Belousov-Zhabotinskii reaction (or BZ reaction)!

The Belousov-Zhabotinskii reaction (or BZ reaction) is performed using a mixture of sodium bromate, malonic acid, sulphuric acid, and ferroin. This creates a complex oxidising reaction that changes colour periodically. The oscillations start with the formation in a red solution of small blue dots that expand into ever-widening concentric blue rings. Sometimes these will become expanding Archimedean spirals; the patterns intermix and become increasingly complex towards the end of the reaction. These waves are not mechanical in the same sense a ripple can be considered; instead these waves show information traveling. from:

So pretty!!!!
