This experiment demonstrates autocatalysis, whereby the products of a reaction act as a catalyst for that reaction. This is the Briggs-Rauscher reaction, although there are other similar pulsing reactions.

Professor Hal Sosabowski is a committed chemistry educator who shows how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
