1 cup All-Purpose Flour
4 cup Water (as 1 cup then 3 cups)
and 1 cup water into a large saucepan. Stir in water until smooth. Add the
remaining 3 cups water and place over medium heat. Bring the mixture to a
sustained boil (cannot be stirred down) for 1 minute then remove from
heat. Let cool. Pour into 3 or 4 separate cups (paper cups, plastic bowls,
etc.) and add food coloring. Store the paint in a air-tight plastic
bowl, cup, or large baggie.
