Unformatted text preview: the mixture, it will act like a liquid. With cornstarch itself, it has a quality that allows for it to absorb the water. When this absorption takes place, barriers are formed that hold the water in the starch molecule. These barriers are flexible but stiffen when force is applied, demonstrating the Non-Newtonian characteristic mentioned. Looking at this example of cornstarch and water is particularly interesting because of its parallel to quicksand. Quicksand acts like the cornstarch and water mixture from the demonstration in that it is also a Non-Newtonian fluid. When one becomes trapped in quicksand, it is usually the first instinct to struggle to get out of it. This, however, adds pressure, making escaping more difficult. The best way to escape quicksand is to move towards solid ground slowly, and to try and distribute ones weight to reduce the pressure....
