Art and Science - swirling colors

Several people have asked how we made this image that we posted on Facebook. So here are the instructions.
Put a little bit of milk in a bowl (or plate or tray or whatever). We use whole milk but 2% should also work.

Add some drops of food color. Don't mix.
Add a drop of dish soap and - watch the colors swirl and move. Here you can see where we dropped the soap (orange oval right in the center of picture).
For an explanation of what is going on, see

More pictures from our playing around with color and milk are below....
