The Magic Milk experiment is a ton of fun! This science activity with milk & food coloring is great for kindergarten and elementary aged kids. By far, one of my absolute favorite parts of my Montessori training were science experiments. Finding creative ways to hook a child, to intrigue him, and ignite his desire to want to learn more about a particular subject really drove me. The Dancing Milk science experiment is one of my favorite experiments to achieve this hook.
Not only is making milk dance fun for kids and adults to watch, but this easy and inexpensive activity also combines science and art and can be done at home or in the classroom. After an explosion of movement, watch this beautiful graceful dancing milk! Have fun!
Why does milk react to soap & food coloring? Here is a brief explanation of the science behind dancing milk.
Milk has fats and proteins within its make up that are sensitive to changes in the substance. In our case, this change came from a drop of dish soap. Dish soap has a bipolar quality to it. This means that dish soap is non-polar on one end and polar on the other. When the soap hits the milk, the soaps bipolar quality weakens the chemical bonds holding the fats and proteins together. The non-polar end of the soap is the center of the party.
The non-polar end “fears” water and this attaches to the fat molecules in the milk. The fat molecules move in all sorts of fun ways as the soap molecules attempt to attach themselves to the fat molecules. The food coloring helps us observe a phenomenon that typically is not visible to us.
