Scientific definitions for quicksand

quicksand
[ kwĭksănd′ ]

A deep bed of loose, smoothly rounded sand grains, saturated with water and forming a soft, shifting mass that yields easily to pressure and tends to engulf objects resting on its surface. Although it is possible for a person to drown while mired in quicksand, the human body is less dense than any quicksand and is thus not drawn or sucked beneath the surface as is sometimes popularly believed.
