At that level of density, sinking beyond about waist height in quicksand is impossible. Even objects with a higher density than quicksand will float on it if stationary. Aluminium, for example, has a density of about 2.7 grams per cubic centimeter, but a piece of aluminium will float on top of quicksand until motion causes the sand to liquefy. [3]
Quicksand forms when water saturates an area of loose sand, and the sand is agitated. When the water trapped in the batch of sand cannot escape, it creates liquefied soil that can no longer resist force. Quicksand can be formed by standing or (upwards) flowing underground water (as from an underground spring), or by earthquakes.
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.
In the "Sink or Float" YouTube game, Cookie Monster and his friend Emma ask for your help in testing whether five different objects will either sink or float in a tank of water.

Quicksand is a shear thinning non-Newtonian colloid that gains viscosity at rest. Quicksand's non-Newtonian properties can be observed when it experiences a slight shock (for example, when someone walks on it or agitates it with a stick), shifting between its gel and sol phase and seemingly liquefying, causing objects on the surface of the ...
Earlier this week, Musk proposed abolishing the Consumer Financial Protection Bureau. “Delete CFPB. There are too many duplicative regulatory agencies,” he wrote on his social media platform, X.
The main danger is being trapped and exposed to the elements in quicksands located on riverbanks, at the base of earthen dams, in abandoned rock quarries, in swamps, etc. Quicksand does not act as in the B-movies of the 1940s or 1950s in which people get "sucked" under the surface: since quicksand is thicker than water, one can float higher in ...
