Could a person walk on mercury? I'm talking about the liquid, not the planet. Since it's so dense, shouldnt you only sink in a little bit so you'd be able to walk?

  1. Mercury's density is 13.5 (a human body is around 1). This means that to achieve buoyancy, 1/13 or so of your body (by volume) would have to be under the level of the mercury surface. This probably means around knee deep on one leg.


  2. no

    we would be able too survive  

  3. I guess if you could learn to balance, but it would be too dangerous (vapours and absorption through the skin).

  4. if the mercury was cold enough it would freeze and you could walk on it.

  5. It would not really be walking, because inherent in walking is pushing off with the back foot.  You cannot push off against a liquid unless it is extremely viscous.  It would be more of a very strange type of swimming.
