For each child mix 1 tablespoon Epsom salts and 1 tablespoon water on a small yogurt lid.  With a spoon, carefully stir in 1/4 teaspoon of the desired food coloring other than yellow. Children can observe the changes over the next few days as the water evaporates and small crystals begin to form. Keep a magnifying glass handy for closer examination.

HINT: Remember to combine colors to make more colors. Also be sure to label each child’s project by placing the lid on a square of paper with the child’s name on it.
