Fiona and her daughters Samantha and Emma explore the beautiful science of chromatography. In this fun experiment to do at home, they reveal the hidden colours inside felt tip pens. As water is drawn up through the kitchen roll, it drags up the colours that make up the felt tip ink. Fiona and her daughters learn that although two inks may look the same, they may be made of different balances of colours. Using their newly learnt skills, Samantha and Emma solve a felt tip mystery, identifying which pens were used to write which letters.

Make beautiful pictures called chromatograms, that show the hidden colours in inks.
ExpeRiment with different pens to see what colour dyes are in their inks.
Learn about the scientific technique of chromatography and how it can be used to solve mysteries.

This series of ExpeRimental is supported by the Royal Society of Chemistry.
