When I squeezed a drop out of each food coloring bottle, the food coloring stayed in place and didn't spread. After I added the drop of soap, the food coloring spread through the surface of the milk. The food coloring moved away from the drop of soap, but it slowed down later on and settled down again. It made a swirly pattern after the experiment went on for a while. Then the food coloring stopped moving after a short time. I added another drop of soap after it stopped, and it started spreading again.
