Fill baby food jars with different colors of sand, making layers. To color your own sand, fill
paper cups half full of sand. Add water to completely cover the sand. Add food coloring for the desired
color. Stir and then let stand 15 minutes. Pour off water and spoon sand onto paper towels.
Spread out sand and allow it to dry completely before using.
