Escaping quicksand youtube how to#

If you try to pull a limb out of quicksand, you have to work against the vacuum left behind. However, quicksand-unlike water-does not easily let go. Quicksand is just ordinary sand mixed with upwelling water, which makes it behave like a liquid. Take the shortest route to firmer ground, moving slowly. The pole will keep your hips from sinking, as you (slowly) pull out first one leg and then the other.ДҐ. Work the pole to a new position: under your hips and at right angles to your spine. After a minute or two, equilibrium in the quicksand will be achieved, and you will no longer sink.Д¤.

(And hopefully you have a pole handy so you donвЂ™t have to hold on to a snake in order to be rescued like poor Indy.) Here is how to escape from quicksand:ДЎ.В When walking in quicksand country, carry a stout pole-it will help you get out should you need to.Дў.В As soon as you start to sink, lay the pole on the surface of the quicksand.ДЈ.В Flop onto your back on top of the pole.

Well, lucky for you, The Complete Worst-Case Scenario Survival Handbook has the answer. You may panic (which is not surprising) and need a quick way to figure out how to get out of your predicament before it is too late. As the bay is very broad and shallow, a person trapped by the quicksand would be exposed to the danger of the returning tide, which can come in rapidly.There may come a time when you are feeling especially Indiana Jones-like and find yourself walking through an area where quicksand is native and suddenly begin to sink into the ground.

One region notorious for its quicksands is Morecambe Bay, Yorkshire. Quicksand may be found inland (on riverbanks, near lakes, or in marshes), or near the coast. Another finding was that a human cannot be drawn into a saltwater quicksand entirely. It increases the high viscosity regions of sediment responsible for quicksand's 'trapping' power. The stability of the colloidal quicksand is changed by the presence of salt. In 2005 it was been shown that the presence of salt is important. Pressure from underground sources of water would separate and suspend the granular particles, reducing the friction between them. It was commonly believed that the behavior of quicksand was due solely to saturated or supersaturated suspensions of granules in water. The forces required to do this are quite large: to remove a foot from quicksand at a speed of one centimeter per second would require the same amount of force as 'that needed to lift a medium-sized car'. In order to move within the quicksand, a person or object must apply sufficient pressure on the compacted sand to re-introduce enough water to liquify it. The viscosity of the quicksand seems to increase suddenly. Around the person dense regions of sand and sediment form and grip the person. Under his weight, the person then sinks into the sol (liquidised sand). There is a sudden decrease in its viscosity. Quicksand is a non-Newtonian fluid: when undisturbed it often seems to be solid (' gel' form), but a small (less than 1%) change in the stress on the quicksand causes it to turn liquid (' sol' form). This makes it difficult to distinguish quicksand from the surrounding environment.

Since the water does not usually go all the way up through the sand, the sand above does not appear to move at all, and can support leaves and other small debris. They behave more like a liquid when exposed to stress. This lubricates the sand particles and makes them unable to support any significant weight, since they move around with very little friction. The water moves up and then down slowly in a convection-like manner throughout a column of sand, and the sand remains a generally solid mass. Water circulation underground can focus in an area with just the right mixture of fine sands and other materials such as clay. Quicksand and warning sign at a gravel extraction site. Quicksand may be escaped by slow movement of the legs in order to reduce viscosity of the fluid, and rotating the body so as to float on one's back (supine). It can be difficult to get out: that is the real problem. A human or animal does not sink entirely into quicksand due to the higher density of the fluid. However, a person does not drown in quicksand. If animals or people stand on it, they sink into it. It has the characteristic of thixotropy: it looks solid, but when pressure is applied it liquifies (acts like a liquid). Quicksand is a mixture of water and sand or silt.
