It's okay to posit a spider of physically impossible size because of Tolkien needed a big damn spider in his text, but not exceptionally low-density lava because Tolkien never noted it in the text itself? If Tolkien had specified in the text that Gollum sunk into the lava, what would your position on it be then?It seemed big because the hobbits were small, maybe only about the size a human. Maybe it had evolved a circulatory system or something.
Holy crap. My understanding is that contact with mercury is dangerous, so I'm guessing sitting on top of a swimming pool full of it means this guy is hurting.Not really. Mercury compounds are poisonous, because they can be absorbed into your body, but touching mercury would be no more painful then touching lead, for example. Metallic mercury doesn't really get absorbed into the body very easily, and mercury poisoning isn't something that people realized could happen right away. People used to actually drink it.
