If you have just a foot stuck in quicksand, gently move the foot back and forth, adding water along the side of your leg. One way to get out of quicksand is to lay back on it and float, much like you would do in regular water. This is because humans are less dense than quicksand. Although humans do initially sink when they first enter quicksand, they cannot sink all the way (only to about chest deep). Panicking, the adventurer tries to quickly pull his or her foot out, only to find that now the quicksand is acting like a solid, encasing the foot all the more firmly in this unpredictable substance.īut don’t worry about getting sucked down into quicksand like you see in the movies. When it is lightly stepped on by the unaware adventurer, the quicksand liquefies and the foot of the adventurer starts to sink. This same principle applies to quicksand. But a high pressure, such as punching firmly, causes the cornstarch-water mixture to act as a solid. A light pressure, such as pouring or gently pressing the cornstarch-water mixture, allows it to move like a liquid. Since the ability of a non-Newtonian fluid to move depends on the force or stress applied to it, these fluids do not act like ones we are more familiar with (e.g. For instance, warm honey flows much more freely (less viscous) than cold honey (more viscous). Unlike quicksand, the viscosity of Newtonian fluids (fluids, such as water and honey, that follow Sir Isaac Newton’s law of viscosity) is dependent only on the temperature and pressure of the fluid, not the force applied to it. Quicksand and the cornstarch-water mixture are both non-Newtonian fluids, meaning that their viscosity changes with the type of force applied to it. The way that a liquid flows or moves is affected by its viscosity. Weird, huh? But the way this cornstarch-water mixture behaves is very similar to how quicksand behaves. But when you tried to move your hand through it quickly or hit the substance very hard, it behaved like a solid. Whenever you gently and slowly moved your hand through the cornstarch-water mixture, it behaved like a liquid. Did the substance splatter everywhere or did it stay put in the bowl? (If it splattered, add more cornstarch.) What Happened: ( Be careful not to hurt yourself on the bowl!) Make sure to hit the substance hard and pull your fist back quickly. Try punching the cornstarch-water mixture. Then try again, this time relaxing your hand and pulling it out slowly. If your mixture is deep enough to submerge your entire hand in it, try grabbing a handful of the mixture and pulling your hand out quickly. Was it easier to move your hand slowly or quickly through it?ģ. Move your hand through the mixture, slowly first and then trying to move it really fast. You should notice that your hand sinks in the mixture like you would expect it to do. After making your mixture, gently lay your hand on the surface of the cornstarch-water mixture. So if you use a regular sized box of cornstarch (about 16 oz), you will use about 1-1/2 to 2 cups of water.Ģ. The approximate ratio of the cornstarch-water mixture is 1-1/4 cups of cornstarch to 1 cup of water. In the plastic mixing bowl, combine small amounts of water and cornstarch together to form a mixture that looks like heavy whipping cream and has the consistency of honey. Since quicksand is normally found along beaches, marshes, and other wet areas, if you can find sand here, you probably have sand with the right grain type to make quicksand.Ī much easier and more dependable way to make ‘quicksand’ is to use cornstarch instead of sand. Ordinary playground sand (the type you can buy in a store) rarely meets this standard. The grains of the sand need to be round in shape and the same size. However, quicksand can also be formed by underground springs or runoff water from heavy rains. The most likely places to find quicksand are along beaches, lakes, rivers, marshes, and swamps because there is a ready supply of water there. The sand and water make a soupy mixture that often looks solid on top, but when it is agitated (by being stepped on) it turns into a liquid. Sand often becomes super-saturated with water when it is deposited in a sink hole or hollow in the ground that is made out of material (such as clay) that does not allow the water to drain from the sand. Quicksand occurs when the right type of sand becomes super-saturated with water.
