I did an art/science project with my 2 year old today and I just had to share. You probably already have the ingredients in your kitchen right now to do it yourself. We were completely mesmerized by this – I heard lots of “wows” from my son. I love it when art and science collide.

Here is all you need: Vitamin D milk, food coloring and dish soap.

What to do: Pour in a little milk into the bottom of a shallow dish

With food coloring, put in drops of different colors in the milk

Then take dish soap and put a small drop in the middle of the food coloring.

You should immediately see the milk react and begin to disperse the food coloring in a colorful display. It’s like a tiny living ocean of color.

Originally I came across the idea via Household Hacker. Here is their explanation of how it works:

Food coloring is less dense than the milk itself – so it remains suspended within the fat molecules of the milk the soap breaks up the fat and lets it spread across the surface of the milk. As they break and expand, they create movement in the milk, and pull the coloring along for the ride.

I don’t know who had more fun, me or my toddler!

So beautiful and intriguing how it all works. I hope you go try it for yourself!
