How to not make a splash

Study adds to understanding of droplet behaviour

New research by a scientist in the US can better explain how a droplet splash is dictated by the smoothness of a surface, as well as the surrounding air pressure.

Scientists already knew that two aspects were involved in this seemingly simple process; one related to the surrounding air, and the other to how the liquid spreads on the substrate. ‘If we were forced to guess, we’d probably assume that decreasing the ambient pressure around the drop would make the splash bigger. After all, we’re decreasing air resistance,’ explains Andrzej Latka, at the University of Chicago, who performed the new research.
