    I wish they wouldn't do the bleeps on this - I kids maybe watching but they've heard all these words before and it's so patronising to the "silent majority" (hah hah!).
    Incidentally Hank is so engaging in his delivery - a delight to hear and watch.

    '“Oh, no you don’t,” is the common reaction of most chemists to that proposal, “. . .not unless I’m at least a mile away, two miles if I’m downwind.” This, folks, is the bracingly direct route to preparing dioxygen difluoride, often referred to in the literature by its evocative formula of FOOF.'
    If you found this episode appealing, try blogs.sciencemag.org/pipeline/archives/2010/02/23/things_i_wont_work_with_dioxygen_difluoride
    It's (one part of the) blog of Derek Lowe, who is, I think, a consultant chemist, and who has a bracing, dry wit. I'm sure he came up in the research for this one.

    "It's much more dangerous to handle than fluorine gas, which, as anyone with a degree can tell you, is not a sentence you get to say very often."
    When a person says something like this, you know they're talking about some really nasty stuff.
