Save your breath: A new way to make bubbles requires only sound waves. Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the ...

Researchers at the University of Bristol, UK, have shown that droplets of liquid can travel uphill when placed on a vertically vibrating inclined plate. 'In fact, if the plate vibrates at the right ...

The fluid dynamical behaviour of liquid drops and bubbles has long fascinated researchers due to its rich interplay between inertia, surface tension and viscous forces. This area of study encompasses ...

Drying drops exhibit a rich phenomenology that depends on the suspended materials, convection and evaporation 1, surface tension and capillary interactions 2, contact line pinning and depinning 3, ...

Physicists have thoroughly investigated the 'coffee ring effect,' the ring-shaped stain of particles left after drops of coffee evaporate. In a article, they have uncovered the complex and remarkably ...
