You Will Need:
Water, cooking oil, food dye set, paintbrush (bigger is better), sturdy paper plates, paper (solid color)
Experiment by mixing food dye colors with water and adding oil to see what happens. Then, add one drop of the dye and oil mixture onto the paper plate and have your child brush the paper with the paint brush. The color of the drop should move gently around the paper with the oil/water mix gliding over the paper.
Cover the surface with newspaper or a craft tablecloth, because the table can become messy and slippery with the oil.
