You need a shallow dish, milk, food colors and dish soap and a Qtip
Pour milk in the dish and then drop in food coloring. Now add a little dish soap to the Qtip and just dab the surface of the milk. Why? The soap moves around and finds the fat in the milk - so that's why it continues to move around as the soap searches out the fat. Comments are closed.
