Graphite (from a pencil lead) is applied to one side of an index card and a piece of the card is immersed in a beaker containing hexane and water (two layers). The graphite-coated side always faces the hexane layer. When the two liquids are carbon tetrachloride and water the graphite-coated side always faces the carbon tetrachloride.
