Washable Spray Chalk - cornstarch and baking soda and food coloring . what a fun way for kids to make art this Summer! Making the chalk takes seconds, and it easily washes off of the sidewalk and other outdoor surfaces
Kool-aid snow paint is super vibrant and smells amazing which makes it even more fun for kids - *Food coloring worked great. Kool-aid would be great but as fast as they go through it, it's just as easy to drop some food coloring and add water.
