Shaving cream and food coloring: First you put the shaving cream on a paper plate and flatten it out then you add drops of food coloring all over it. We took a wooden skewer and made vertical and horizontal lines to create this look. After making the lines you put a piece of construction paper over it, press down a little, lift and wipe off with a paper towel. The food coloring sticks after the shaving cream is wiped off. We used primary colors and then tried it again with secondary colors.
