It’s rarely more than a few feet deep and the worst that can happen, in most situations, is you lose a shoe! If you do fall into quicksand, you shouldn’t panic. Until you step on it - surprise, surprise.
#Quicksand gif how to
How to escape quicksandīecause the water seeps in from the bottom, the top layer of sand is often dry, causing it to look like any normal sand. Then you’re exposed to the sun, cold and even starvation.
Quicksand can indeed become dangerous maybe even life threatening if you’re all alone and don’t know how to get out. When placed on a quicksand made in the lab and stirred through shaking, Taz predictably sinks but never completely. This plastic Taz has the same density as an average human body. “Although you are trapped, you cannot drown,” says Bonn who placed various objects in a quicksand mixture and these never completely submerged. Their research, however, puts to rest an old myth about quicksands. Strikingly, to pull a foot out at a rate of 1 centimeter per second would require the same force needed to lift a medium-sized car, Bonn and colleagues found. Just a 1% change in stress caused the viscosity of the mixture to drop by a factor of nearly a million, essentially turning the quicksand from solid earth to gooey liquid. His research shows that quicksand is highly sensitive to the forces applied to it. Quicksand is a shear thinning non-Newtonian fluid which looks like a gel when undisturbed but quickly drops in viscosity once an object rests its mass.ĭaniel Bonn of the University of Amsterdam in the Netherlands and the École Normale Supérieure in Paris, investigated what makes quicksand so puzzling: easy to get in, hard to pull out. While quicksands can be found all over the globe, there are naturally some areas that are more prone to host them like riverbanks, beaches, lake shorelines, near underground springs or marshes. This is why sometimes you hear of buildings sinking even by more than a foot following an earthquake - a home literally trapped in quicksand. Earthquakes or some other high vibration source can increase the pressure of shallow groundwater through shaking, thus liquefying the soil. If an underground reservoir can flow upward through loose sand and get around each grain, then friction is lost and the whole grainy soil becomes a suspension, with the grains floating around the water.
Most often, this is the likeliest source of quicksand formation.
One of the following situations can lead to the formation of quicksand: Quicksand can appear virtually anywhere in the world if an area of loose sand is saturated by water and becomes agitated. ADVERTISEMENT What quicksand is and how it’s made
