Today we’re going to be talking about chromatography; a process that will allow us to see the different colours hidden in black ink.
For this experiment you will need: a glass, a jug of water, a black felt tip pen, a paperclip or clothes peg, scissors, and some absorbent material like tissue paper or a coffee filter if you have one. You'll also need some adult permission and supervision. Ideal for ages 5 and over.
