Students won't believe their eyes as they watch this amazing oscillating reaction!

Concepts: Oscillating reactions, equilibrium. Time Required: 20 minutes to 1 hour Chemicals Provided: Potassium bromate solution, malonic acid/ potassium bromide solution, cerium ammonium nitrate/sulfuric acid solution, and ferroin solution.
