The cushioning of water gives quicksand, and other liquefied sediments, a spongy, fluid-like texture. This causes the sand to form a suspension and lose strength. The saturated sediment may appear quite solid until a sudden change in pressure or shock initiates liquefaction. In the case of upwards flowing water, seepage forces oppose the force of gravity and suspend the soil particles. Quicksand can form in standing water or in upwards flowing water (as from an artesian spring). When the water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support the weight. Quicksand forms in saturated loose sand when the sand is suddenly agitated. Quicksand may be found on riverbanks, near lakes, in marshes, or near coastal areas. In the dimension of "Jumanji", Quicksand serves as a natural trap for herbivores or predators, leading to either drowning from total submerging or dying from exhaustion trying to drag themselves free. Quicksand is a colloid hydrogel consisting of fine granular material (such as sand, silt or clay), and water.
