Super Scientist Brooks did a great experiment about surface tension. He used half and half milk and then had each student drop different colors of food coloring on top. He did not mix it up. Instead, he poured drops of dishwashing liquid on the drops of food coloring. Immediately, we could see the milk swirl the colors together. It was very cool to see the various colors forming as they were mixed. The class also thought it was neat that it continued to swirl all day on its own. Awesome experiment, Brooks!
