If immiscible fluids occur together, they segregate according to their densities: the lightest (least dense) fluid floats to the top, and the heaviest (most dense) sinks to the bottom of the container (or compartment). When they occur in a container free of [[capillary effect]]s—such as a bottle, lake, or cave—the different fluids exhibit a sharp, flat interface.
