Find out what is quick sand and what is the best way to get out of it.Basically, a quicksand is a colloid hydro gel consisting of fine granular matter (such as sand or silt), clay, and salt water. Water circulation underground can focus in an area with just the right mixture of fine sands and other materials such as clay. The water moves up and then down slowly in a convection-like manner throughout a column of sand under optimal conditions, and the sand remains a generally solid mass. This lubricates the sand particles and renders them unable to support any significant weight, since they move around with very little friction, behaving more like a liquid when exposed to stress. 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, making quicksand difficult to distinguish from the surrounding environment. Quicksand is basically just ordinary sand that has been so saturated with water that the friction between sand particles is reduced. The resulting sand is a mushy mixture of sand and water that can no longer support any weight. If you step into quicksand, it won't suck you down. However, your movements will cause you to dig yourself deeper into it. In this article, you will learn just how quicksand forms, where it's found and how you can escape its clutches if you find yourself hip-deep in it. Quicksand is typically not very dangerous, but it’s one of the last things you’d want to run into if you were sand boarding. Check out the sand boarding article, video and images at Discovery’s Fearless Planet to learn more. "With quicksand, the more you struggle in it the faster you will sink. If you just relax, your body will float in it because your body is less dense than the quicksand." When you try pulling your leg out of quicksand, you are working against a vacuum left behind by the movement, according to The Worst-Case Scenario Survival Handbook. The authors of the book advise you to move as slowly as possible in order to reduce viscosity. Also, try spreading your arms and legs far apart and leaning over to increase your surface area, which should allow you to float. Here's a video that I've found on YouTube. This video actually summarised everything above: Here's the link: http://www.youtube.com/watch?v=JHCW_bqWLTo Reference links: http://en.wikipedia.org/wiki/Quicksand http://science.howstuffworks.com/quicksand.htm |
