Each year at its annual meeting, the American Physical Society's Division of Fluid Dynamics sponsors a contest for the best images in a variety of categories, all related to the flow of fluids.
Saad Bhamla was in his backyard when he noticed something he had never seen before: an insect urinating. Although nearly impossible to see, the insect formed an almost perfectly round droplet on its tail and then launched ...

When a stationary droplet containing a solute in a volatile solvent evaporates, the flow in the droplet can assemble into complex patterns. Researchers have examined such transport in evaporating sessile droplets in solvents. ...
Liquid droplets assume complex shapes and behave in different ways, each with a distinct resonance—like a drum head or a violin string—depending on the intricate interrelationship of the liquid, the solid it lands on ...
