Is quicksand real?
quicksand Quicksand and warning sign at a gravel extraction site. Enlarge Quicksand and warning sign at a gravel extraction site. This article is about the geological feature. For other meanings, see Quicksand (disambiguation) Quicksand is a hydrocolloid gel consisting of fine granular matter (such as sand or silt), clay, and salt water. When unperturbed, it often appears to be solid; however, even a minor (less than 1%) change in the stress on the quicksand will cause a sudden decrease in its viscosity. After the initial perturbation – such as a person attempting to walk on it – the water and sand in the quicksand separate and dense regions of sand sediment form; it is because of the formation of these high volume fraction regions that the viscosity of the quicksand seems to suddenly increase. 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 liquefy it. The forces required to do this are quit

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 liquefy it. 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.” [1] It was commonly believed that the behavior of quicksand wa
Yes, they are real. Quicksand are round shaped sands that when something is over it they move fast. since they are circular, the object above it move to the bottom quuickly, thus quicksand is being named. If ever you do fall on a quick sand, the best way to do is don’t move and wait for somebody to help you out. for as you move you will go further in the bottom and i you find a chance to grab on something stable that will pull you up from the sand. Then pull yourself up and your safe just avoid that area soon.
