When mixed together the two subsances form a new substance. Typically it is the transformation of an acid to a base, which cause the indicator within the formula to change colour, deceivingly like magic.

Materials:
 * Potassium Iodate
 * Sodium Bisulfite
 * Distilled water
 * Soluble Starch
 * 1.0M Sulfuric acid

Procedure:
 * Prepare Potassium Iodate and Sodium Bisulfite
 * Pour solutions into seperate containers
 * Mix Solutions, allow the two to combine
 * Explain how the solution has changed to a base which cuses the indicator to change colours.
