"You can get out using this technique, if you do it slowly and progressively. This creates a space between the legs and the quicksand through which water can flow down to dilate the sand," he explained. So, this offering is a great way to add value to any sinking video collection. Quicksand has a density of about 2 grams per milliliter, whereas the density of the human. Krystal is special, and so was this location. Quicksand itself is harmless: a human or animal is unlikely to sink entirely into quicksand at all due to the higher density of the fluid (assuming the quicksand is on dry ground and not under water, but even if underwater, sinking is still impractical). "The way to do it is to wriggle your legs around. Krystal looks and acts smoking hot as she slips neck deep into bottomless ooze She is the star of the most viral quicksand video in history, but here is a chance to see her sinking much slower, and for pleasure this time. So how do you get out? Don't ask your friends to tug on you they're likely to pull you "into two pieces if try hard to pull out," said Bonn, a physics professor at the Van der Waals-Zeeman Institute at the University of Amsterdam. "I would say there would be some pressure on the chest, but not enough to cause serious trouble." Girl Sinking in Quicksand / Quicksand Girl / Quicksand / Girl in Quicksand Girl Sinking in Quicksand this youtube video. If you do step into quicksand, says study co-author Daniel Bonn, you'll only sink in a little deeper than your waist. The authors estimate that the force needed for someone to pull their foot out of quicksand at a speed of a centimeter a second would be the equivalent of that required to lift a medium-size car. Water has to be introduced into the sand sediment to loosen it, and this requires considerable amounts of force. It's the difficulty of moving this dense sand that causes the problem. The increase is due to the formation of sand sediment, which has a very high viscosity. Difficult to Get Out Ofīut if quicksand becomes less viscous as you struggle, why is it so difficult to escape? The reason, explain the study's authors, is that after its initial liquefaction, quicksand's apparent viscosity (thickness or flow resistance) increases. Thats what you get for recognizing that you were up to your ankles in quicksand and deciding that that would be the perfect time for doing a series of hip rolls. But when they shook the container a bit harder, the ball descended to the bottom. ohmigawd, Im like, totally sinking in quicksand you guys. When they shook it only a little, the bead stayed floating on top. At rest, the bead remained on the surface, despite aluminum's higher density.īut then scientists started shaking the container. But a piece of aluminum will float on top of quicksand until motion causes the sand to liquefy.ĭuring their study, researchers placed an aluminum bead on top of a container of laboratory-created quicksand. Aluminum, for example, has a density of about 2.7 grams per milliliter. You would descend about up to your waist, but you'd go no further.Įven objects with a higher density than quicksand will float on it-until they move. At that level of density, sinking in quicksand is impossible. But human density is only about 1 gram per milliliter. Quicksand has a density of about 2 grams per milliliter.
