Easy Experiment: Watch as food coloring swirls in milk

Beth Harris, a Raleigh mom, long-time science educator and creator of Fort Kits for Kids, is back with another easy experiment we can do at home with the kids.

This one requires a pie pan, milk, food coloring, dish soap and a toothpick. Watch the video to see Harris explain how it's done. And check the More on This section for other activities.
