Is quicksand real?
Yes. Quicksand is a colloid hydrogel consisting of fine granular material (such as sand, silt or clay), and water. Quicksand forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support weight.

Is quicksand dangerous?
Nope. Quicksand—that is, sand that behaves as a liquid because it is saturated with water—can be a mucky nuisance, but it's basically impossible to die in the way that is depicted in movies. That's because quicksand is denser than the human body.

Is quicksand a solid or a liquid?
The Oobleck mixture isn't your typical liquid—or solid. The cornstarch-and-water mixture creates a fluid that acts more like quicksand than water: applying force (squeezing or tapping it) causes it to become thicker. ... Share your Oobleck observations and results!

Is quicksand in the desert?
Yes. Dry quicksand. 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 is an example of a granular material.
