Our chromatography science experiment today - circles drawn with washable felt-tip pen on kitchen paper, then transformed with a spoonful of water dropped into the centre. This one is black ink, but it is pretty strange to see all the coloured dyes used to make it up.

H was unbelievably excited by the whole process, and then I even got her to come to the allotment with me in the rain!
