Water, Acetone, Ether, Drop a steel razor blade onto the surface of each liquid and see on which one the razor blade stays afloat., Water, Acetone, Ether, The density of the three liquids is approximately the same but the density of steel is almost ten times that of the liquids. However, the razor blade floats on the surface, because of the high surface tension of water.
