Rome, Piazza del Popolo, the lions of the central fountain expectorate a turbulent water sheet. Random velocity fluctuations in the liquid nucleate holes which, driven by surface tension, grow and merge, leaving the sheet as a set of connected ligaments. These corrugated ligament further breakup into a collection of disjointed droplets broadly distributed in size.
