milk science

We checked out some fun science project books from the library the other day. While this activity didn't last us very along, it was easy, amazing, and very beautiful. All it takes is:

milk
food coloring
a toothpick, or something similar
dish soap

You pour some milk into a shallow pan. Add several drops of food coloring. Then dip the toothpick in the soap and touch it to the milk.


The colors suddenly swirl and shoot around the pan. Very cool.
