Materials ~ litres of distilled water ~ 29g potassium iodate ~ 1L 3% hydrogen peroxide ~ 8.6mL concentrated sulfuric acid ~ 10.4g malonic acid ~ 2.2g maganese(II) sulfate monohydrate ~ 0.2g soluble starch ~ 20g sodium thiosulfate ~ 2 1-litre beakers ~ gloves ~ hot plate ~ 2 Stir rods ~ 100mL beaker ~ 50mL beaker ~ 3L beaker ~ magnetic stirrer  Procedure


 * Solution A is 1 litre of 3% hyrogen peroxide
 * Solution B is created by placing 20g of potassium iodate and 400mL of distilled water into a 1 litre beaker. Then add 8.6mL of 6.0M H2SO4 then warm and stir the solution until the potassium iodate dissolvs. Dilute the soluton to 500mL with distilled water. The solution is now 0.27M in KIO3 and 0.1M in H2SO4.
 * Solution C is create by dissovling 10.4g of malonic acid and 2.2g of maganse(II) sulfate monohydrate in 400mL of distilled water all in a 1 litre beaker. In your 100mL beaker heat 50mL distilled wate to a boil. In a 50mL beaker, mix 0.2g of soluable starch with 5ML of distilled water to form a sort of slurry. Pour the slurry into the 100mL beaker then continue to heat and stir the mixture until the starch dissolves. Then pour the beaker into the 1 litre beaker. Dilute the solution to 500mL with distilled water. This solutin is now 0.2M in malonic acidand 0.026M in MnSO4
 * After all solutions are created pour solution A and B into a beaker placed on a magnetic stirrer. Adject the stirrng rate to create a large vortex. Pour in solution C and watch your experiment.
