Take a thin strip of filter paper.
Draw a line on it using a pencil,
approximately 3 cm above the lower

Put a small drop of ink (water soluble,
that is, from a sketch pen or fountain
pen) at the centre of the line. Let it dry.
Lower the filter paper into a jar/glass/
beaker/test tube containing water so
that the drop of ink on the paper is just
above the water level, as shown in Fig.

Watch carefully, as the water rises up
on the filter paper. Record your
observations​
