Water forms droplets because attractive interactions between molecules produce surface tension. If macroscopic objects—say, grains of sand—replace the molecules, the relative strength of this attraction would dramatically drop.

Researchers at MIT recently found an elegant solution to a sticky scientific problem in basic fluid mechanics: why water doesn't soak into soil at an even rate, but instead forms what look like fingers of fluid flowing downward.Scientists call these rivulets "gravity fingers," and the explanation for their formation has to do with the surface tension where the water"”or any liquid"”meets the soil (or other medium). Knowing how to account for this phenomenon mathematically will...

Scientists said on Wednesday they have discovered how tiny insects manage to walk on water and propel themselves across the slippery slopes of ponds and puddles.

University of Arizona physicists have discovered what it takes to make metal 'nanowires' that last a long time. This is particularly important to the electronics industry, which hopes to use tiny wires -- that have diameters counted in tens of atoms -- in Lilputian electronic devices in the next 10 to 15 years.
