Liquids that float in other liquids! When oil spils happens in sea, it floats in the surface of the water because it doesn't mixture with water and it has a lower density. In the present experiment we can observe that the water floats in a known fluid. That fluid is the honey, being the densest liquid of the group that were analyzed. The water is the second denser liquid analyzed, being heavier than the olive-oil and ethyl alcohol, and lighter than the honey. Not surprisingly, the olive-oil floats in water, having a less density than it. The olive-oil doesn't float in alcohol and, therefore, is heavier than it. In relation to the ethyl alcohol, this is the liquid that presents the smallest density of those analyzed.

Picking up the same volume of each one of the analyzed liquids, the one with higher density (bottom) would have a larger amount of matter (mass) per volume unit. In contrast, the alcohol would be the reverse.
