This is an entry for the Gallery of Fluid Motion of the 65st Annual Meeting of the APS-DFD (fluid dynamics video). This video shows the motion of levitated liquid droplets. The levitation is produced by the vertical vibration of a liquid container. We made visualizations of the motion of many droplets to study the formation of clusters and their stability. 


From bouncing to floating: noncoalescence of drops on a fluid bath.
An analysis using lubrication theory accounts for most of the observations, showing that a steady regime where a drop can be kept bouncing for any length of time is found.
