Yes, I know... it's been ages, but what with Rob being in hospital, and sorting out stuff related to that with school, I've not done the Grand Catch-up I intended to.

Still, having seen him off to school (and chased Tara off to work), I'm indulging myself with a little newsreading. And what do I find, but a paper that gives plausible explanations for firewalking, gargling with N₂(l) and the trick my old science teacher did with molten lead: Boiling and the Leidenfrost Effect. Oops:I should have mentioned that it's a PDF document.

Guess I'll do that catch-up later...
