So this is a really straight forward activity and a very sticky one as well! I first saw the idea here: ECE Made Easy. I poured sweetened condensed milk into various sections of ice cube trays leaving open spots to mix new colors. Then I added red, yellow, and blue food coloring to a couple of spots in each tray. I left one spot with no color to use to lighten other colors.
Then I mixed them with toothpicks and handed them over to the girls to paint with. Again I used watercolor paper since it is much thicker then normal paper.
Nadia enjoyed painting.
Bria enjoyed the mixing.
Since it was all edible I let Eli in on the fun. He liked painting....
He actually had to have a bath by the end of it.
Luckily once the milk dries it isn't really sticky anymore, but it does stay shiny!
