Quicksand: do you know what??????

Quicksand: do you know what??????

How many times I watched the films is the heroine in the pit of quicksand.

If the US hero was not saved himself in the final minutes through the dangling part or an old tree branch and pulling himself out?
If you are authenticated to the displays in these movies, you believe in the existence of a large Monster inside this hole swallows everything to the lowest point on Earth

But no.

The true qualities of quicksand is not the same as in the movies.
Quicksand is not a frightening force of nature that you see on the big screen. In fact, quicksand is rarely deeper than several feet.
If one of us ventured a couple in a quicksand will dive a little bit down.
The higher the person's movement caused by time in the sand.


What is quicksand?

Quicksand is a natural phenomenon.
Is a solid ground turned to liquid due to waterlogging.
Word (animated) refers to easily shift and moving the sand when you are near liquid (sticky).

Quicksand is not a specific type of soil is sand only or grainy soil.
It is not only a mixture of sand and water to swim in water and sand floating on the face.

When gather water and sand in the pit, one cannot force them and melt water and soil surface appears dry and sand but in fact saturated sand cannot bear any weight of situated.



There are two ways to be quicksand:

• Method 1:

The flow of water from underground water Flowing underground water flowing upward from the ground to resist and overcome the force of gravity.

• Method 2:

Earthquakes shake the ground force increases the pressure on the aquifer (shallow), by which melts sand and destroy the foundations of buildings on beaches and shores alanharlanh lose durability surfaces, causing landslides.

Vibration in earthquakes increase, so are responsible for dismantling and facilitate the movement of sand in buildings according to Dr. Larry Baron of the New South Wales Geological Survey.
Then water and vibrations resulting from earthquakes that cause reduce friction between sand particles and transformation of sticky situation.
Likely a quicksand phenomenon in certain places than others to waterlogging like

Riverbanks
Beaches
Border Lakes
Marsh

It is possible to turn sand beach to the shifting sands easily only if you pay the right amount of water it which will reduce friction between sand and where the foot will sink if the weight by



How to save man himself if in quicksand pit?

If you find yourself in the pit of quicksand-God forbid-don't worry it will swallow you all and it's not hard to get out of them as you expect.

The density of the human body almost 62.4 lb/cubic foot (1 g/cubic centimeters high) and can the density that is floating in the water.
Quicksand the densest water density almost 125 pounds/cubic foot (2 g/cm cube) which means that the float in quicksand easier to float in the water.
Important to not afraid and disrupted and begins to move his feet and hands and hit the Randomize

"If any deep quicksand up to waist would be difficult to extricate itself from the high density will affect"
So RI as in geological engineering wotn stratigraphy.

If you move yourself with random movements, will increase your rate of quicksand.
The best thing to move in slow motion as I could to the surface or party and then lying down and you'll find yourself reaching safety

When a person in quicksand must reduce his movement as much as possible because he "strongly resisted it will sink, but slowly and slowly move it will survive," said scientists also advised Dumouchelle, try moving the parties from each other and reduce traffic as much as possible because when driving by, for example, must wait until resolved sticker and place sand but will dive into the rest of his body more and tries to make the surface area is as large as possible.
And after all this the result will be the only bad will to boot will be full with wet sand
