Quicksand facts
So, you can float free?

Mythbusters already checked this myth...
But even by thinking about it logically you'd have to conclude that you'd float in quicksand. Sand is denser than water, and quicksand is a mixture of sand and water, therefore quicksand is denser than water. Humans have about the same density as water, and so have a lower density than quicksand, and so would float. |

IIRC this was a point in one of Piers Anthony's books, you can float on quicksand.

If sand is denser than water, then it can't be suspended in water, unless something is keeping it suspended.
Most "quicksand" is actually mud. Clay. Clay chemistry is complex. Clays like montmorillonite expand enormously in water and can produce a viscous slurry that is simultaneously mobile and sticky. Get into it and you may have great difficulty getting out. Mix that with a running sand and you have something that forms a rather effective trap. Now add a bit of darkness, rain, possible local flooding and maybe garnish with tree branches and vegetation washing in ... and just relaxing and floating out may be a lot harder than it sounds. But the idea of being sucked under is false, except in the rare case of a mud / sand slurry overlying a deeper current. Thats more likely in mud slides or tsunamis. All in all, it's not at the top of my worry list. |

Don't worry, Tarzan will always rescue you.

Ever wonder what sort of view you get as he swings overhead on a liana, wearing a loincloth?

Piles of grain are more like the stereotypical movie idea of quicksand in that workers in silos can easily be covered in a matter of moments if its flowing, e.g. the bin is being emptied.

I've stumbled into the stuff. The problem is, even though it is denser than we are, its still easy to sink down to your waste. I've had to be pulled out a few times.

When did you learn lemmings don't really commit mass suicide? Vitamin C doesn't cure or prevent a cold? You don't catch a cold from being cold? Betsy Ross didn't really sew the first flag?
There are thousands of such myths that become 'common knowledge'. It's my principle to trust but verify if it isn't a fact I've recently checked. I fail to see what the problem is with that. |

I spend a lot of time at a "lake", parts of which have at least ten feet of mud (the longest pole we've tested with) beneath one foot of water. If you fell in flat you could float or swim, but feet first and too far from the boat to hold on to it, and I think you'd be dead. Just walking out from shore as the sand gives way to mud, it gets pretty scary when you get into two feet of mud beneath two feet of water.

You can, and will, be sucked down to your death in quicksand but only if you are a
villan. "Good guys" always have a rope/vine, sidekick, hot woman to save them. More often than not a good guy is able to save himself by strengh alone. Women seem to be totally immune to the evils of quicksand. |

You know what's scarier than quicksand?
A floating pool cover. If you get on one of those, you start to sink and the plastic envelops you, like a hideous jelly-fish. Pretty dangerous deal. |

I will never forget one of those films from the 50s or 60s where the supposed jungle queen (a white girl, no less, but who was supposed to be surviving in the jungle just fine before the Tarzan-like hero found her, it may not have been Tarzan) was rescued on average about every 15 minutes throughout the movie.

My son-in-law is an engineer that gets sent out to trouble shoot power plants.
He told me of one job wherein there was a vat of tiny glass spheres. i forget what type of power plant, or the purpose of this pool-sized container of nearly-liquid glass balls...but he had to enter it to repair something. He ended up buying a cheap blow-up raft to get in there. i would have loved to know what its like to try to swim under that sort of artificial liquid...and if you could breathe under it, due to all the air in the spaces. i want a fake water swimming pool, and i want to breathe under the surface of it, and even sleep in it. Too bad the tiny glass spheres are so expensive. |

I guess the Jungle Queen was a serial movie from the 30s. I must have seen the reruns.

No quicksand scene in that 10 minutes but the stereotypes are priceless. I'm sure if one looked for a while one could find a quicksand rescue scene. Here's the 'not quite so PC but they tried' modern remake with Sheena, Queen of the Jungle. It's another priceless rescue scene, this time with quicksand:

I saw a condemned film where the white girl in the jungle was the only female wearing a bra. All the natives were free-jiggling. It was a German film.. 'long 'bout 1958... Us Catholic boys went to see it knowing it was condemned! It was written in the school paper. Some nuns had gone to it, not understanding the theme.. and were appalled! |

You're a Catholic?
Christ, I should have known. I saw Tarzan and his mate on TV in the late 50's or early 60's, and Jane did a nude underwater seen that almost popped my eyeballs out. How did the censors miss that? It was the first breasts I'd ever seen, not counting National Geographic. |

My brother and sister and I all got stuck in a pool of muck when I was around 9 years old. About 3 feet deep. It took me about 2 hours to get out of it, only 6-7 feet or so from the edge. I lost my pants and my shoes, my sister lost everything but her shirt. Luckily our shirts were pretty long and we were covered in mud. Had to walk home 2 miles. Our clothes and shoes are still under there, alongside the run off ditch from a turnpike.

I'd seen a couple of condemned movies before that one... and wondered WTF is the problem with the National Legion of Decency? Didn't seen anything worth a mortal sin in any of them, and today, they'd be considered ho-hum, even on prime time tv. The language was certainly a lot milder. |
