When they reach the bottom of a soap dispenser, frugal handwashers might try adding water to the bottle to push out the last ...

When two fluids don't mix well, they sometimes form strange patterns called "viscous fingering," or Saffman-Taylor instability. Studying these patterns can help scientists understand how to design ...

Honey is already a pretty thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs ...

Modeling the behavior of liquids is important for a wide range of applications, from industrial processes and medical devices to computer graphics and visual simulations. However, despite many years ...
