Despite density differences, oil and water get along just fine when it comes to these experiments. This article explores the relationship between oil and water and provides brief experiments (including materials needed; procedure instructions; and evaluative questions) relating to: making layers with liquids; dropping a few objects in a tall glass of various liquids and find out which layer "captures" them; discovering how to float an egg in water; and seeing how egg whites can be used to help oil mix with water.
