All you need to start is a dish of milk (the higher the milk fat the better), several drops of food coloring in different colors, some dish soap (thats in the little dish) and some q-tips.
All Hannah had to do to get the colors swirling is dip the q-tip into the dish soap and then into the milk mixture. DO NOT STIR, just dip. Hannah stirred hers until it was a lovely shade of grey.
I love the pretty colors and swirly pattern we got, I think Hannah and I will have to try this again soon.
Another variation is to drip the liquid dish soap directly into the bowl for greater movement and swirly effect. So next time I think we will try it that way.
Why does the color swirl???? I looked it up and I really liked Steve Splangler's explanation, check out the link if your interested.
