Quicksand is a colloid hydrogel consisting of fine granular material (such as sand, silt or clay), and water. Quicksand forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support weight. Quicksand can form in standing water or in upwards flowing water (as from an artesian spring).
Not quite. While quicksand isn't nearly as dangerous as it looks in the movies, it is a real phenomenon. Just about any sand or silt can temporarily become quicksand if it is sufficiently saturated with water and/or subjected to vibrations, such as those that occur during an earthquake.f you step into quicksand and you're wearing a backpack or carrying something heavy, immediately take off your backpack or drop what you're carrying. Because your body is less dense than quicksand, you can't fully sink unless you panic and struggle too much or you're weighed down by something heavy.
