Science: Chemistry: Separating Mixtures
Age 7 to 13
Exploration rather than explanation. Have fun while learning science.

This experiment uses paper chromatography to separate the different coloured dyes in felt tip inks.
Chromatography is also widely used in areas like forensics and developing new vaccines.
