The "Briggs-Rauscher reaction," often misremembered as the "Brigg Rouche reaction," is a famous chemical demonstration known as the Briggs-Rauscher Oscillating Clock Reaction, where a solution cycles through colorless, amber, and dark blue, demonstrating complex non-equilibrium chemistry. Discovered by Thomas Briggs and Warren Rauscher in 1972, it involves iodine, malonic acid, hydrogen peroxide, and starch, creating visible oscillations as different reactions temporarily dominate, showcasing pe
