Can you escape the quicksand?

Quicksand is a curious phenomenon, but it does not function as a suction well that swallows everything . They are actually a colloid hydrogel, made up of a mixture of finely granulated material (such as sand or mud), clay, and water. Basically it is a mixture of fine sand (40% -60%) and water, and that is why they are usually found in swampy areas and near estuaries, lakes or rivers.


They behave like a thixotropic or non-Newtonian fluid . In other words, when they are not disturbed by any external factor, they remain viscous like a glue or a solid matter of a gelatinous type, but, being saturated with water, the friction between the grains is minimal, so they work like a mud that cannot bear no weight . If someone steps on it, the water and sand separate, and the mixture becomes fluid. This initially causes the body to sink, but it can come out if you remain calm and follow these recommendations.


Before an external agent intervenes, the sand grains and the water are united , which gives the mixture a viscosity that keeps it stable. As you step on the sands, your body weight alters the tension between its elements, and the mix becomes more fluid . The body of the unwary who enters them tends to sink. It must be taken into account that the force required to get out of them is too great: to move a foot in the quicksand at a speed of one centimeter per second requires the same force that must be invested to lift a medium-size car ( exerting a force of more than one ton).


So instead of walking, what you have to do is push yourself up and back with your arms and lie on your back to distribute the weight of the body and offer more body surface. Thus, the body, being less dense than sand, floats. Then you have to slowly crawl and crawl backwards out.

The best way to prevent a fatality is to have a mobile phone charged and on top and use it to call for help. If you have to wait, move your legs to make the quicksand more fluid as you try to sit on them to increase the amount of your body on the surface.

You can find quicksand all over the world as long as the conditions are right. It is most common near the coast, in swamps or on the banks of rivers. Quicksand can form in standing water when saturated sand is shaken or when soil is exposed to water flowing upward (for example, from an artesian spring). They also often accompany earthquakes, as vibration and the resulting solid flow have been known to engulf people, cars, and even buildings.

Dry quicksand may be present in places like deserts and has also been reproduced under laboratory conditions. Scientists believe that this type of quicksand forms when very fine sand forms a layer of sedimentation over more granular sand. Dry quicksand was considered a potential hazard during the Apollo missions. It can exist on the Moon and Mars.

Slaves and Disabled: Forced Medical Test Volunteers

The main problem to carry out medical research is to have willing volunteers for it. And if they come out for free, much better. This is the story of unethical behavior in medical research.
