    Hi all
    I've been watching the series The Human Universe and in epidose 2 there's a great experiment which shows an indicator changing colour in beautiful patterns, apparently as a reaction goes forwards and backwards.
    Unfortunately the video doesn't mention what the reaction or the reactants are.

    Can anyone help? It's at about 15:20 if you're watching the full video
