The Effect of Dish Detergent in Milk - honorsbiologylabs

If detergent is placed in a sample of 2% milk and f ood coloring, then the colors should swirl faster and more violently than that of the control (whole milk), because 2% milk is less dense (less surface tension) and contains less milk fat (and substance) than whole milk. Therefore, the detergent breaks down the substances in 2% milk faster than that of whole milk.
