First, spray a layer of shaving cream onto some sort of containable surface. We used cookie sheets since they have a lip around the sides. Disposable aluminum baking trays are a good option, too.
|Some used more shaving cream than others :)|
Take a flat object...spatula, knife, piece of cardboard or plastic and flatten the foam down so you have an even surface.
Then add drops of food coloring
Next, take a toothpick and use it to swirl the color around. Don't push all the way down...you want to keep the dye close to the top.
Press a piece of paper onto to surface so it soaks up the color and then peel it off. We used white card stock.
We put our papers outside for a while to dry.
They spent a good chunk of time playing with the foam and mixing colors.
Then we took paper towels and wiped the shaving cream off the papers.
