www.Primo.com: You know quicksand.

Sands of life are the most unique mechanism of the universe, it may be buried on the banks of the river shore or even perhaps in the back yard around it, calmly waiting for people approaching, making it difficult to go forward or backward. Some mysteries of sand suction :

In 1692, at the port of Jamaica, never happened sands of life are formed from the soil solution due to the earthquake, the news caused the third city of the lost, and the tragedy that killed 2,000 men.

The lake was calm in the south of England, fjords or narrow bay in Alaska beautiful but dangerous and other areas had occurred human life trapped in the sand.

However, most people probably have never come across the sand of life, let alone witnessed people stuck in the sand live or experience it for yourself. Impression of the people against the sand live mainly based on various movies they watch. Mood or scene is created in the film depicts life sand is a scourge that can suck people into the bottomless pit.

It would dissolve if the surface of the quicksand disturbed.

A scientist from the University of Amsterdam, The Netherlands namely Daniel Bonn ever meet a local shepherd. The pastor pointed quicksand saying in Bonn, that was never a camel fell into then disappeared without trace.

Then he immediately related investigation after returned to the country. He brought samples of sand to the Netherlands and analyze its composition. Having found that the mixture consists of high-quality sand, clay, water and salt, the experts and his team create derivative quicksand in large quantities.

They observe and analyze carefully dozens of films that depict views of quicksand that swallows man, and found that the picture painted these films entirely erroneous.

Then, in the laboratory, experts mixing sand, clay and salt water, forming a sand mockups live in a small room for examination. After repeated experiments, personnel researchers found that it took a few days to make the sand becomes sticky.

Instead it is easy if you're going eliminate viscosity (viscosity), which is sufficient given the right pressure at the surface. The surface will be "dissolved" quickly if you get a movement disorder, the sand on the surface will be loose (mushy), and sand in shallow layer will also drop down quickly.

This displacement movements create a moving object on the surface of the sand sinks to the bottom, then along with the increasing depth of the drownings, sand falling down through the displacement movement of the top layer will slowly converge, and will create a thick sediment, so that the viscosity or the nature glue sand accelerating, preventing further mired object.

It takes strength to lift a car.

According to the research, that people are mired in quicksand generally can not move, which increases the density of the sand and then glue on the lower limbs were mired in quicksand, forming enormous pressure on the body, making it very difficult exertion.

People who are very great strength is also difficult even in a short time can remove victims trapped in the quicksand. After the calculation of the relevant researchers, that to remove one leg trapped victims with a speed of 1 cm / sec just need the power of 100 thousand Newton, or roughly equivalent to the power lift a medium-size car.

Unless assisted by Derek car, if not difficult to extricate victims trapped in quicksand that in a short time. Related research results also showed, according to the count of this force, if forcibly dragged the victim, then before quicksand "release" trapped victim, the victim's body has been broken attracted by the great powers.

Risks resulting from such action is much more dangerous than allowing victims to remain in the quicksand that for a while.

How to save themselves from the trap.

Actually most of the quicksand is not much different from the sand in general, not creepy as depicted in the film. In principle, it is only sand that has been infused water, because of friction (friction force) between the grains of sand is reduced, so that it becomes a mixture of sand and water half the liquid that is difficult to support. Sands of life are usually found around the coast.

According to experts, there is only one state that quicksand can drown men (drowned), when the head of the first to get into, but chances are mired in this way is very small. People who are mired in quicksand only feel a slight pressure on the chest, a little hard to breathe, would not life-threatening. The tide in the sand near the new life terrifying enemy for trapped victims.

People misinterpret that by shaking legs to loosen the sand around the body, thus can help the members of the body to get out of the sand. Related scientists said, is actually not so, such movement will only accelerate the deposition of clay, strengthen the viscosity (viscosity) of quicksand, struggling blindly will only make the victim more deeply mired.

An expert said that the way to escape from the sand remains, namely victims trapped should slowly move his legs, so that water and sand as much as seeping into the hollow area, so it will be able to reduce the pressure from the victim's body, and makes the sand so that the soil becomes loose long.

In addition, the victim must also trying to keep his limbs apart, because if you touch the sand surface area greater weight, then gained buoyancy will be even greater. Provided that the victim had enough patience, the movement is fairly quiet and relaxed, then slowly surely will be free from the trap of quicksand.

In addition, the research also found, when an object is mired in quicksand, the setting of the speed is determined by the density of the object. Live sand density generally 2 milliliter, while the human density is 1g / milliliter. Under such density, the human body is immersed into the sand of life will not drown, often will stop until the waist.

In addition, the researchers also found that although the number of objects greater density than the sand of life, but still able to float on the sand of life. In a related experiment, they then put the aluminum ball that density 2.7g / ml above the surface of the quicksand.

Although the density is greater than the sand of life, but as it gets influence of buoyancy quicksand and sand voltage, then the aluminum ball can remain calm on the surface of live sand. The ball did not sink until the researchers thrilling quicksand and make movements that cause more fluid mixture. When doing this, the aluminum ball really entirely submerged.

However, when using aluminum ball that has a density similar to humans, which means lower than the density of quicksand, the ball never sink though the mixture treated rudely.

The fall of the object into quicksand cause water mixed with sand particles lose stability. If it continues to be pressure, the mixture will turn into more liquid on the surface and very solid at the bottom.

The greater the pressure, the more fluid formed in quicksand so that movement of the victim make it fall deeper and deeper.

Based on the measurement of this aluminum equipment, physical pressure to increase by 1 percent particles causing the sinking speed riding a million times. The researchers added that the draw objects of quicksand at this stage requires the equivalent power of a medium sized car lift.

Be patient and calm.

The most dangerous is when quicksand tend to draw quickly. But, patience can save you. If you wait patiently, sand particles will gradually stabilized so that the buoyancy of the mixture will lift you up.

We know that the sand layer beneath it more tightly while more water in the upper layer. Very dense sand layer below contain very little water so difficult removing foot fall into it.

His advice, stay calm and usually you will float. Straighten your back to expand the free area and wait until the legs are free of sand.

The experts also suggested that the foot moves to control the water so you float. You must enter the water into the sand and the easiest way is twirling around feet in quicksand.

Suggestions are most likely correct. The proof, the aluminum ball in this experiment did not sink more than half. Although the ball only four millimeters in diameter, density equal to humans that can be used as a human model.
