Study: Stream of sand behaves like water
University of Chicago researchers have discovered dry granular materials such as sand, seeds and grains have properties similar to liquid.
The physicists from the university's Materials Research Science and Engineering Center said the granular materials form water-like droplets when poured from a given source. The researchers said their finding could be important to a wide range of industries that use
fluidized dry particles.
The research that included graduate student John Royer is reported in the June 25 issue of the journal Nature.
