It drops into a glass container filled with water, spreads like volcanic smoke, and gradually disappears.
A work of impermanence and indefinite repetition.

Molecular clock is a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged.
It is sometimes called a gene clock or an evolutionary clock.(wiki)
