Chromatography




















Today we worked at chromatography at Petite. Use coffee filters or paper towel to break apart secondary colours. Using water soluble markers, place two dots on your paper. Then place the paper in a glass of water so that the water wicks up the paper and and seperates the ink into its different dyes.


You can also test kool-aid to see which kinds of dyes have been used.
