Mix together the water and cornstarch, and stir until the cornstarch dissolves.
Divide the paint mixture into the wells of a muffin tin or similar painting tray.
Add food coloring to achieve the desired colors – note that the colors will dry much lighter on the sidewalk than they appear in the tin!
Large brushes work best!
