Part 2 Pour the six liquids (from part 1) into the same graduated cylinder (to the left). The liquids are immiscible and will separate into distinct layers by density. Correctly drag and drop the liquids and put them in the correct order in the graduated cylinder. Put the colored rectangles (liquids) into the correct empty rectangles in the graduated cylinder (numbered rectangles). Densest liquid will be on the bottom. The least dense liquid will be on the top. 6 5 4 3 2 1 Harrisonite Wheelernone Waltonium Osborneum SAMSUNG Kellese Popebrillium
