Color Changing Milk

This visually vibrant activity demonstrates what happens when dish soap weakens the bonds that hold fats and proteins suspended in milk. Perhaps you can have chemistry lab groups perform this activity when they are learning about solutions, polarity, hydrophilic and hydrophobic molecules, or chemical bonds. Maybe they can even experiment to find out if different fat content in milk affects the motion. It will definitely add color to the class!
