Water: a video full of woo

[Lonewulf]

I don't think water's unique in that respect, but other substances that do that are extremely rare. Water's the only substance I know that is more dense as a liquid than as a solid, but I suspect there are others.

I seem to recall that solid D2O will sink in ordinary water, but will float in liquid D2O.

Well, floating in liquid D20 instead of H20 is much more important, after all. The premise is being lighter than itself in solid vs. liquid form, not another compound.

Folks, I'm branching out a bit as a wootective. Any background info you can point me at that summarizes who Rustum Roy fellow is and what he (mis)represents? I know I can use the search function here, but I'm hoping that someone might have centralized info, sort of like what Gravy and a few others have done for 9/11 conspiracy peddling. From my 9/11 CT subforum participation, I'm having trouble detecting whether he's the equivalent of Steven Jones (misstates evidence and misconstructs the significance of what he discovers through his own research), Richard Gage (argues from his authority as an architect, but doesn't well support his statements with actual analysis), David Ray Griffin (misrepresents facts to draw conclusions from them), or James Fetzer (full on crock; hears the cuckoo clock sounding midnight at all hours of the day), and it's sort of an interesting challenge for me to find that out. From his mangling of a basic freshman-level chemical concept, I doubt that he's actually a trained scientist who's fallen off his rocker, but I do have Steven Jones as an analogy that shows such a thing is possible.

IIRC, Rolfe and Badly Shaved Monkey are the heavy-weights on this topic. This thread isn't a bad intro (if you can stand it).
