Death can come in the form of suffocation, dehydration, hypothermia, predators, crush syndrome, or drowning from a river or incoming tide. Even though you can't sink all the way into quicksand, it's a killer.However, a person or branch can be used to help reduce the victim's weight, making it easier to work free and float. A rescuer can't simply pull a victim out of quicksand.Really, the only way to drown from the quicksand is to fall into it head first or face first. You can only sink into quicksand up to your waist.It changes its viscosity in response to stress or vibration, allowing you to sink, but making it hard to escape. Quicksand is a non-Newtonian fluid made of sand mixed with water or air.
