So... Friday afternoon I mixed up 1 cup water, 1 cup cornstarch, and then added some food coloring. I placed the liquid chalk into a muffin pan and it worked out really well.
Ben and I had some paint brushes laying around, so we handed those to Elizabeth and told her to have fun. She has asked me about 10 times a day when she is going to be able to paint the driveway again. I think we will have to make this a regular project. :)
Elizabeth checking out the colors
Every color of the rainbow!

We moved to another part of the driveway, to paint some more
She loved it!
