    I don`t know the specific chemicals, but I`ve done something similar to this in a chem class. After mixing the initial two chemicals, they react to make two compounds in a solution, which then react with each other to make two different compounds in a solution, which then react to make the initial two compounds in a solution.

    Here you are.

    "In 1973, the spectacular demonstration was perfected by Thomas Briggs and Warren Rauscher, two amazing high school science teachers.

    Over thirty-five years later, chemists are still trying to fully understand how it works.

    What they do know: Several reactions take place at once. One of them produces iodine, which gives the amber color. Hydrogen peroxide reduces other chemicals into iodide ions. Along with normal iodine, the charged particles interact with starch to create it a blue-black color. The speeds of those transformations are constantly changing. As one overtakes the other, the color suddenly changes. "

    As the name indicates, this is an oscillating reaction.

    Two or more reactants are put into solution, they react with each other to produce two more more new chemicals, THESE chemicals react with each other to produce the original reactants.

    The solution has to be heated because this would be a perpetual machine otherwise, since one of the reactions must give off energy and the other take in energy...hence the heat to provide the energy for the reaction to go "backwards".

    Hopefully that explains it for everyone.

    If I`m not mistaken this is the Belousov-Zhabotinsky Reaction or more commonly called the BZ reaction. Mainly goes from yellow to blue just like in the video. I`m not going to explain the chemistry behind it because its incredibly boring and I don`t fully understand it. I`m doing a chemistry degree but I`m only in the first year.

    hmm. I did a biology practical exam the other day using milk and other chemicals, and when all mixed together they went bright pink :] Once another chemical was added, they went white again.
    Its not as impressive as that, but it was one of the most fun exams ive ever had.

    I know how this happens! Finally a use for the information;
    The yellowish color is from the production of the I2. The I2 forms because of the rapid production of HOI during the radical process. When the radical process is occurring, HOI is created faster than it can be consumed. Some of the HOI is used while excess is reduced by hydrogen peroxide to I-. The increasing I- concentration reaches a point at which the nonradical process takes over. However, the nonradical process does not produce HOI nearly as fast as the radical process, so the yellow color begins to clear as I2 is consumed more quickly than it can be created. Eventually the I- it drops low enough for the radical process to restart so the cycle can repeat itself.

    The deep blue color is the result of the I- and I2 binding to the starch present in the solution.

    It ends up staying pretty dark, after entropy stops, but this is by no means perpetual. It only lasts for maybe 5 minutes under constant heat.

    Reminds me of something I did for a school lab. We studied type 1 substitution reactions in organic chemistry. Some fast color change occured just like in the vid. As for it to change back though, it didn`t matter. We had to time the whole thing and do calculations involving a bit of calculus. I aced the report for this thing!

    I don`t know all the details, but at a certain point the reaction reaches a stage called equilibrium, causing the reaction to reverse and start again, this is the cause of the colour change.
