You need: 2-4 ice cube trays, food colorings, small rubber or plastic animals, plastic containers.
Fill ice cube trays with water, drop a few drops of food coloring into each opening and freeze.
Fill one tray with water, drop a rubber animal into each opening and freeze.
Fill plastic containers with water and freeze.
After everything has been frozen, drop the various chunks of ice into a large plastic box. Use the colored ice to draw with ( paper or sidewalk) and try to find a way to get the rubber animals out of the ice chunks.
