Original Kurzfassung:
The present paper discusses a special type of solutal driven Marangoni flow. It was previously shown that certain combinations of substrate liquids plus alcohol-water mixtures can lead to the production of a large number of micro droplets. The size and spreading radius of the micro-droplets can be manipulated by the concentration of the alcohol. As the experimental setup is very easy to reproduce it can (i) serve as a simple test case for student courses to discuss various aspects of Marangoni flow and (ii) could be elaborated as a convenient way to produce droplets of a certain size in future micro-fluidic applications.
