Stumbling into a quicksand seems to be a scary predicament. Thanks to movies and television which gave these sink holes a bad reputation. However, a real quicksand will not suck people all the way in. But getting out in one can be difficult.
Contrary to its depiction in media, a man who is stuck in a quicksand will only sink to his waist, elbows or armpits, depending on how much he weighs and what he is carrying. Objects in a quicksand will sink only to the level at which their weight is equal to the weight of the displaced sand/water mix. In fact, humans will float in quicksands!
