Corn starch, water, food coloring, muffin tins, and some foam brushes. I bet you don't even have to go buy anything. I mixed up a real thin solution of corn starch and water in a pyrex measuring cup, poured the white "paint" into the muffin tins. I added a few drops of food coloring to the solution when it was separated in the tin so I could do different colors. Less than five minutes, seriously.

Pour in boiling water and stir between each cup until it becomes a custard like consistency. Separate into different jars before adding coloring **perfect for infants
Sidewalk chalk paint is so much cooler than regular old sidewalk chalk! And it’s crazy easy to make! It’s simply 1 part cornstarch to 1 part water. I made two muffin tins of paint and used 1-1/2 cups cornstarch and 1-1/2 cups water. Once it was all mixed up, I divided it among the 12 muffin cups, and added two drops of food coloring to each muffin cup
