Buoyancy helps. 🧐 engineering
", colloids like quicksand do not follow the normal laws of physics associated with liquids and/or solids. Interestingly, there are plenty of examples of similar non-Newtonian fluids in your home too.
This leaves a layer of densely packed wet sand that cannot support your weight and causes you to sink. This is primarily because the frictional forces between sand grains that would normally be able to resist your weight are temporarily lubricated. Certain places are prone to quicksand formation like, for example, hollows at the mouths of large rivers, along flat stretches of stream, beaches where pools become partially filled up with sand, or other dense material prevents drainage. Quicksand can also be found where sand, mud, and vegetation mix together in bogs., however, you can never actually completely become submerged in quicksand. This is because quicksand, while a hazard, cannot defy other basic laws of physics — namely buoyancy.
Interestingly, some scientific experiments have been conducted in the past to attempt to simulate and study quicksand under more controlled conditions and without risking anyone's life. One particular example was conducted byWhile on a trip to Iran, he came across a body of quicksand near a lake. Bonn took some samples and analyzed them back in his lab. clay, saltwater, and sand, and decided to make more of it synthetically.
