We’ve all seen the movie where the character gets stuck in quicksand and slowly sinks to the bottom resulting in his untimely death or last minute rescue.
In reality, quicksand is denser than water. The greater the density, the greater the buoyancy of objects within. Any victims found in quicksand likely died for some other reason (i.e. exposure to the elements). Quicksand is rarely deeper than a few feet. If you step into it, it won’t suck you down but your movements will cause you to dig yourself deeper into it. If you relax your body , you will float in it because your body is less dense than the quicksand.
