Ashlie Miller from The Paint Cellar shows us how to make your own liquid sidewalk chalk and stencils.
Assorted Food Coloring
Pour equal parts baking soda and corn starch into a water bottle until it’s 2/3s full. Add several drops of food coloring (you can always add more if you want it darker). Fill the rest of the way with water. Shake to mix or stir with knife or long handled spoon (whatever you can fit inside your bottle). Fill a separate bottle with vinegar.
Squirt liquid chalk on sidewalk. Once you have your pretty design then squirt the vinegar onto it and watch the magic happen!
