Here is an oscillating reaction in a puddle. All reagents in the Briggs-Rausher (B-R) reaction must be free of chloride ions, which inhibit the reaction. here is the recipe for the large scale version
• Solution A: 10 vol hydrogen peroxide solution.
• Solution B: 6% (w/v) potassium iodate(V) solution in 0.1 M sulfuric(VI) acid.
• Solution C: 1% starch solution.
• Solution D: a solution containing 2% (w/v) malonic acid and 0.45% (w/v) manganese sulfate(VI).
• Add the solutions to a beaker on an magnetic stirrer in the following order and quantities: 20 ml of solution A, 20 ml of solution B, 1 ml of solution C and 20 ml of solution D.
