What is milk art?

Milk has fat in it and the food coloring floats on top of the fat. The fat is all connected with bonds. Think of it like the little pieces of fat all holding hands with each other. When you add the dish soap to the milk, the fat separates and moves making your magical milk art!

Why does dish soap repel food coloring in milk?

Detergent, such as liquid dish soap, is mostly surfactants. As the soap spread out from the cotton swab, it decreased the milk’s surface tension around it, and the higher surface tension surrounding this area pulled the milk (along with its food coloring) toward it.

Why does the color changing milk experiment work?

Since milk is mostly water, it has surface tension like water. The drops of food coloring floating on the surface tend to stay put. Liquid soap wrecks the surface tension by breaking the cohesive bonds between water molecules and allowing the colors to zing throughout the milk.

What happens when you add food coloring to milk?

The milk is made mostly of water molecules, but it also has fat molecules and protein molecules which are bigger than water molecules. This causes the detergent molecules to zoom out in every direction over the surface of the milk and push the food coloring out toward the edge of the plate.

What happens when you put dish soap in milk?

When liquid dish soap is added to milk with drops of food coloring on the surface, the soap reduces the surface tension of the milk and reacts with the fat. This interaction causes the fat particles in the milk to move and create swirls of color.
