We played color
mixing game a long before and here is our color separation experiment. Chromatography is a process of separating
color pigments and it will help us to show how primary colors are mixed
together to make the secondary colors.
The experiment
is very simple. Take a filter paper and draw something in the middle using
sketch pens or non permanent markers.
Put few drops of water in the middle and wait for some time. When the water moves in the filter paper due
to capillary action, it separates the color pigments. Black and brown colors are the best for this
experiment. You can repeat the
experiment with different colors and different brands of sketches.
