Prof Hal Sosabowski shows us a stunning and surprising reaction, by mixing three colourless solutions. This demonstrates autocatalysis, whereby the products of a reaction act as a catalyst for that reaction. The reaction here is the Briggs-Rauscher reaction, although there are other similar pulsing reactions. Prof Hal Sosabowski is a committed chemistry educator, evangelist and communicator. Hal shows us how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
