Answer:
A wick is taken and a spot of ink is put at one of its ends and the wick is dipped in kerosene. The color spot has been successfully separated into its constituent colors but at different levels due to the sharing of different affinities of the components of the liquid for kerosene. This process is known as chromatography, performed to separate mixtures dissolved in a liquid.
