A Discovery Channel show called Mythbusters covered quicksand.  In all the 
experiments that they did, they discovered that with fine sand on top of a 
powerful spring, you will sink, but only until the point where you normally 
become buoyant in water.  It will not suck you under.  You only get screwed 
if the water is shut off when you are down to your chest and the water 
stops welling up.  Then the sand settles and you are entombed.
