        In the Belousov-Zhabotinski reactions a cerium salt is mixed with
a malonic acid and potassium bromate.If the mixture is stirred, at certain
rates of adding chemicals, the system begins to turn blue, then after a
few minutes red, then blue again, and so on, oscillating between red and
blue.
        I dont have experimental data, try a search on the Web(yahoo,alta
vista,excite,for example)or on the Bids.
        Good luck!
