Liquid Lace, Phred Petersen, RMIT University
This photograph illustrates the Marangoni effect, seen here in the break-up of a drop of glycerin-water mixture impacting a thin film of ethanol. Surface tension gradients between different liquids force the flow in the direction of higher surface tension, creating holes in the normally smooth ejecta crown. This flow effect can also be seen in the ‘tears’ in a glass of wine.
