Spectacular Soap

The Science Behind It

Different liquids react differently when mixed. Milk consists mainly of water. It also contains fat. Some fluids will be repelled by one another, moving away from one another. Others will be attracted to one another and form bonds.

The soap in the cotton ball is designed to break and split fat up, which is why we use it for washing plates. When the soap interacts with the fat in the milk it breaks its bond with the water and appears to push it to the side of the dish. This is because it has broken the surface tension of the water.
