Liquid sidewalk chalk
I made liquid sidewalk chalk for the girls to paint the driveway. It paints like water colors, but dries bright like chalk. And it's a simple recipe - equal parts water and cornstarch, plus a few drops of food coloring.
Molly liked painting with all the different colors.
Leah had a lot of fun painting the cement, but eventually moved on to her hands, and the front door! It's a good thing the paint was washable.
