Answer:

1. Draw a pencil line across the filter paper, 1 - 2 cm from the bottom.

2. Use a pipette or capillary tube to add small spots of each ink to the line on the paper.

3. Place the paper into a container with a suitable solvent in the bottom. For example, water. Make sure the water level is below the pencil line.

4. Allow the solvent to move through the paper, but remove the chromatogram before it reaches the top.

5. Allow the chromatogram to dry.

Extras : preferably use a lid to prevent evaporation and use a pencil or any suitable device to prop the paper in place, make sure the sides of the paper doesn't touch the sides of the beaker.
