This may be too trivial an example, but you can demonstrate an oil slick by filling a clear glass container about halfway with water, then adding an inch (or less) of salad oil. Then stir the whole thing. Although the surface of the water, below the oil, will be disturbed, the oil will remain smooth or nearly so. This experiment shows why it's so hard to remove an oil spill from the surface of a body of water.
