Colourful Butterflies

We made chromatography butterflies today. We started by marking coloured dots with felt tip pens. Then we put the bottom of the paper in a shallow tray of water and watched the water soak up the paper. We were amazed as the colours seemed to “melt” and spread upwards. Some of the colours even changed – the brown spread out in to blue and orange for example. We noticed that our patterns were the same on both wings.
