Abstract

All of us have seen it: a raindrop running down the windowpane. It stops at a certain point, is met by a second raindrop and the two join up before continuing to run down the pane. Very small irregularities or dirt on the windowpane appear to stop the course of the raindrops. If the surface was entirely smooth and chemically clean, the raindrops would be able to flow unhindered. Surface defects such as small bumps and dimples as well as chemical contaminants stop the liquid drops.

These are everyday phenomena everyone knows and can observe with the naked eye.
