When we did the chromatography first we had to cut pieces of paper and put a dot of colour on the paper close to the bottom and dip it into the liquid and watch it expand and grow towards the top there were 9 pieces of paper and each of them had different colours

We used acetone for the permanent marker colours
we used meths/water for the felt pen markers colours
We mixed up our colors so we don't know what ones are felt pen and what ones are permanent marker
