Fun with food coloring, soap, and milk

We've now had 2 days of cold and wet weather.  Baby Chuck and I try to go out in the mornings, but we usually stay at home in the afternoons because parking spots are so difficult to find.  (Curse you, parallel parking!)

So... what's a cooped up mama and 16 month old baby to do?

Well, yesterday we tried another food coloring activity.  This time we found Steve Spangler's amazing science page.  He had a demonstration that involved food coloring, dish detergent, and milk.   Look what we were able to do:

Ooh.  Psychedelic!

Materials:
- milk  (we used whole... but I bet you could use other types of milk... but the intensity may differ...)
- bowl / container
- food coloring
- dish soap
- cotton swab
