You are at your neck in quicksand.Every frantic movements makes you sink deeper in the quicksand.It is like a life creature, swallowing you alive. Finally you whole head gets suck under the quicksand. Vision becomes imposible and you feel your nose and mouth cloging up with vile mud. You are seeing spots behing your eye, your brain is creaming for oxygen. You take a deep breath but get more mud stuck in your throat, slowly clogging up your lungs and goes into your body systems and you lungs are burning on fire, fighting, fighting to get oxygen......



That is indeed a rather terrible way to die. trust me, you do not want to die in quicksand. but before we go screaming our heads off about how scary quicksand, lets talk about what is quicksand.

Quicksand:
Quicksand consist of fine sand , clay, and salt water. Water circulation underground focus in an area with just the right mixture of fine sands and other materials such as clay. The water lubricates the sand particles and mkaes them unable to support any significant weight, since they move around with very little friction,due to the water lubraicating the sand and it behaves more like a liquid when there is a rather significant weight acting on it.The water does not lubricate all the sand, leaving the sand above to appear to not move at all.It can support lightweight objects (eg.leaves) and makes it a rather good camouflage thus we are not able to distinguish the quicksand from the environment.


Properties:
If we step on quicksand, we will immediately start to sink. To remove a foot from quicksand at a speed of one centimetre per second would require the same amount of force as that needed to lift a medium-sized car. Imagine if you were to lift your whole body out of quicksand and one foot requires the strength needed to raise a car? the whole body to raise you out of the quicksand would require the strength needed to lift a moutain!

Imagine, just water , sand and clay could create such a strong thing. Nature doesn't fail to amaze me. 0-0

To get yourself out of quicksand, we should spread our arms and legs wide and reach out for something. lets just hope you don't get into quicksand eh?
