- A friend and I tried to calculate the relevant facts about this late one
- night last week. I think we decided that your foot would sink in, and
- then the extreme weight of the mercury would crush your foot.
- Basically, you will displace enough volume of mercury to equal your
- weight, which is more than enough to cover your foot. It would also be
- mighty slippery, so you would probably slip and hurt yourself pretty
- badly. Since i don't remember the exact density of mercury, which is
- easy enough to look up, I'm not sure exactly how far you'd sink, but it
- would be enough to hurt you, i think. It'd be hard to walk when you're
- sunk into it, also.
