In this laboratory experiment, high school students are challenged to prepare a six-layered chemical "rainbow" in a test tube. Students start with six unknown, colorless liquids and six pigments ranging from violet to red. The experiment is problem based and forces the students to apply their knowledge of solubility and density and combine it with creative and critical thinking to come up with a successful strategy to make the rainbow. This is followed by experimental testing to find the unique solution. Finally, coloring and correct layering of the liquids produces the final and aesthetically pleasing result, a chemical rainbow.
