So here is the problem, you are given four liquids, each has a different density. You are not allowed to measure the mass, or the volume. You cannot use any numbers. You have to make an educated guess as to which liquid is denser. The liquids are different colors, so if you pour them into a test tube one will float atop the other, but if you pour a denser liquid onto one less dense, they will mix. Good Luck, and thank you soo much to anyone who answers this question with any real ideas. Will post back telling you if it worked :). You cannot use any math. (I know, it would be so easy otherwise) I have thought that testing two solutions together and seeing if one would float, because then at least I would have eliminated some of the 24 possible answers, but is it possible to narrow it down further?
