A group of hikers encountering quicksand on the banks of the Paria River, Utah Quicksand warning sign near Lower King Bridge, Western Australia. Quicksand is a shear thinning non-Newtonian fluid: when undisturbed, it often appears to be solid ("gel" form), but a less than 1% change in the stress on the quicksand will cause a sudden decrease in its viscosity ("sol" form).
Natron can be used to dry and preserve fish and meat. It was also an ancient household insecticide, and was used for making leather as well as a bleach for clothing. The mineral was used during mummification ceremonies in ancient Egypt because it absorbs water and behaves as a drying agent.
Dry quicksand is loose sand whose bulk density is reduced by blowing air through it and which yields easily to weight or pressure. It acts similarly to normal quicksand, but it does not contain any water and does not operate on the same principle. Dry quicksand can also be a resulting phenomenon of contractive dilatancy.
While salt may make quicksand less stable, quicksand may be found along the banks of rivers, at the base of dams, and over springs where fresh water flows up through the soil. There are many examples of freshwater quicksands. The description of quicksand should not be limited to salt water. Naaman Brown 18:17, 30 July 2007 (UTC)
