Caption: A graduated cylinder containing 6 liquids, four of which seem to be somewhat immiscible: maple syrup is at the bottom and olive oil is a the top.

The "chemical differentiation" is due to the buoyancy effect---placed in a fluid, objects rise/sink/float neutrally if the are less/more/equally dense as the fluid.

The tendency of some of the liquids in graduated cylinder to dissolve into each other prevents 6 clean layers from forming in the "chemical differentiation".
