Quicksand
Quicksand is a colloid consisting of fine granular material and water. It is impossible for a human to sink entirely into quicksand due to the higher density of the fluid. To remove a foot from quicksan at a speed of 0.01ms would require the same amount of force as needed to lift a car.
About Quicksand in brief
Quicksand is a colloid consisting of fine granular material 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. It is impossible for a human to sink entirely into quicksand due to the higher density of the fluid. The popular perception that humans can be completely immersed and drown in quicksands is physically impossible.
To remove a foot from quicksan at a speed of 0.01ms would require the same amount of force as needed to lift a car. Quick’sand is often depicted in adventure fiction, particularly in film, where it is typically depicted with a suction effect that causes people or animals that walk into it to sink.
