The Briggs-Rauscher reaction is a striking oscillating chemical reaction known for its rhythmic color changes between clear, amber, and deep blue. This reaction involves potassium iodate, hydrogen peroxide, and malonic acid, with manganese sulfate as a catalyst and starch as an indicator. In cycles, iodine is produced and consumed, causing color shifts: clear when iodine forms, amber as it reacts with malonic acid, and deep blue when iodide ions complex with starch. The reaction continues these
