basically drown everybody evident simple thanks
Everybody thinks, thanks to Hollywood, that you can drown in quicksand. Basically if you do a simple buoyancy calculation, the Archimedes force, it is immediately evident that you can't drown completely.
difficulty floating foot loose move packing pull sand top water
If you move into the quicksand, this loose packing will collapse. We then have densely packed sand at the bottom, and water floating on top of it. It's the difficulty of getting water into this very densely packed sand that makes it difficult for you to pull your foot out.
body causes higher liquid movement quicksand sink trapped
The higher the stress, the more liquid the quicksand becomes, so movement by a trapped body causes it to sink in deeply.
