Give the kids their new sidewalk paint and let them have fun!
Use up the paint on the same day you make it, this recipe doesn't save well... it will explode if you leave it closed.
If you are going to let it dry after the kids are done painting with sidewalk chalk, then I suggest using the washable paint as it is easier to clean then using food coloring. If you are going to wash it soon after having the kids color with it then use the food coloring.To clean the paint off your driveway or sidewalk, just grab the garden hose and spray they artwork off. If you let it dry it will be harder to remove and it might stain but the sun will remove any color left behind with time.
