Milk Mixture Mayhem
Milk is mixture that includes several substances including water, vitamins, minerals, proteins, and tiny droplets of fat suspended in solution. Many of these molecules have positive and negative electric charges in different parts of their structure. When detergent is added to the milk mixture, the negative part of the detergent molecule lines up with the positive ends of the water molecules. This attraction causes the detergent molecules to move out quickly across the surface of the milk. Initially, there is lots of movement as the detergent and other molecules twist and turn around and different parts of the molecules come together. Along the way, the food coloring molecules are pushed and shoved in all directions interacting with other molecules and creating the colorful and unexpected show.
