First thing you should do is drop your bags or gear. The less weight you pull, the better. Also, try pulling off your shoes as these create friction when you try to pull out of the quicksand. If you get one foot stuck, try to move backwards. It takes a minute for the sand to become liquefied, so you still have a bit of time left before you get stuck. Why, you swim of course. Position yourself horizontally and lean on your back. Kick your legs slowly to loosen the sand around them and then try to gently bring them up towards the surface.
With your hands slowly paddle with short strokes on the surface, being careful not to submerge the hands else you might get them stuck. Aside from getting yourself dirty and losing your shoes or backpack, quicksand is nondeserving of its reputation. That should belong to its much scarier cousin, dry quicksand. Dry quicksand forms when grains of sand form a very loose structure that can barely hold its own weight, let alone yours.
Scientists make it by blowing air through the sand. If an object of meaningful density is dropped on the sand, it will instantly sink and the whole sandy structure will collapse like a house of cards. Once this process is initiated, the energy from the collapse triggers a jet of sand whirling upwards. Aluminium ball takes less than a second ms to become completely submerged! Was it easier to move your hand slowly or quickly through it?
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. Then try again, this time relaxing your hand and pulling it out slowly.
Did you notice a difference? Try punching the cornstarch-water mixture. Be careful not to hurt yourself on the bowl! Make sure to hit the substance hard and pull your fist back quickly.
Did the substance splatter everywhere or did it stay put in the bowl? If it splattered, add more cornstarch. Whenever you gently and slowly moved your hand through the cornstarch-water mixture, it behaved like a liquid. But when you tried to move your hand through it quickly or hit the substance very hard, it behaved like a solid. Weird, huh? But the way this cornstarch-water mixture behaves is very similar to how quicksand behaves. The way that a liquid flows or moves is affected by its viscosity.
Quicksand and the cornstarch-water mixture are both non-Newtonian fluids, meaning that their viscosity changes with the type of force applied to it. For instance, warm honey flows much more freely less viscous than cold honey more viscous. 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. A light pressure, such as pouring or gently pressing the cornstarch-water mixture, allows it to move like a liquid.
But a high pressure, such as punching firmly, causes the cornstarch-water mixture to act as a solid. This same principle applies to quicksand. When it is lightly stepped on by the unaware adventurer, the quicksand liquefies and the foot of the adventurer starts to sink.
Strong forces stiffen quicksand, making it more like a solid than a liquid, so pulling and jerking only make a bad situation worse. A quick Google search reveals most writers don't have personal experience with quicksand or consult water rescue experts. Quicksand can kill! It's true you don't sink in quicksand until you're submerged. Humans and animals typically float in water, so if you are standing upright, the furthest you'll sink in the quicksand is waist-deep.
If the quicksand is near a river or coastal area, you can still drown the old-fashioned way when the tide comes in, but you won't suffocate with a mouthful of sand or mud.
Dry quicksand presents its own special risks. There are reports of people, vehicles, and entire caravans sinking into it and being lost.
Whether this has actually occurred is unknown, but modern science considers it possible. In the movies, escape from quicksand often comes in the form of an outstretched hand, underwater vine, or overhanging branch.
The truth is, pulling a person even yourself out of quicksand won't result in freedom. Removing just your foot from quicksand at the rate of 0.
The harder you pull on a branch or a rescuer pulls on you, the worse it gets! Quicksand is no joke and self-rescue isn't always possible. If you step into quicksand, you should:.
You don't need to visit a riverbank, beach, or desert to explore the properties of quicksand. It's easy to make a homemade simulant using cornstarch and water. Just mix:. If you're brave, you can expand the recipe to fill a kiddie pool. It's easy to sink into the mixture. It's nearly impossible to suddenly pull free, but slow movements allow time for the fluid to flow!
