this is another video by me today.
This is the first one. The bottom one is the rectangle chromatography paper. Some parts of it is fast-forward so it may look very wierd. And the liquid that is poured into the tube is not water but ethonal . they did draw the line but they used permarnent marker instead of pencil and thus, don't need to add the ink. the colours that is shown is unlike ours which is like 1 line but theirs filled up the whole paper and the colours are totally different from the start. o.olll
