Home experiment 1

Here's an interesting chromatography experiment which you can do it yourself at home.
You need:
A piece of filter paper or Kitchen Towel
A bowl or flat plate of water
Some felt-tip pens

1. Put some spots of ink about 3 cm from the bottom of the paper

2. Hang the paper over a bowl of water so that the water touches the paper but not the ink spots.

3. The paper absorbs the water. As the water reaches the blobs of ink, the dyes in the inks dissolve and are carried upwards. The dyes that dissolve most easily travel furthest.
