** Safety: ***Important*
== Wear disposable gloves and safety glasses. H2O2 is corrosive and can burn the skin. Oxygen is evolved in this reaction, so do not perform this demonstration near an open flame. As it produces a fair amount of heat, do not lean over the cylinder when the solutions are mixed. Leave your gloves on following the demonstration to aid with cleanup. The solution and foam may be rinsed down the drain with water **. **==

** Materials: **

 * 50-100 ml of 30% hydrogen peroxide (H2O2) solution
 * saturated potassium iodide (KI) solution
 * liquid dishwashing detergent
 * food coloring
 * 500 mL graduated cylinder
 * splint (optional)

** Method: **
1. Dish soap is placed in large flask with 20 mL of 30% H2O2 (HYDROGEN PEROXIDE). 2. Two different colours of food colouring are dribbled down the neck of the flask. 3. Add 5g KI (POTASSIUM IODIDE) powder and ** step back **.
