    Co2 in gaseous form does tend to elute depending on pH. When it is bound to a benzene molecule you need energy to break the covalent bonds. Thus the heat and pressure.

    The way I had it figured was why buy tea?...drink pyro.
    Art is a step from what is obvious and well-known toward what is arcane and concealed.

    Dr. Johnson drank at least a pot a day, so it could also make you into a brilliant curmudgeon.

    You mean I could become a curmudgeon without all that bothersome study and practice?? Wow - sounds like you are on to something!

    Well, the thought was appealing to me in part because I have a tin of green tea that doesn't agree with me, but I'm too cheap to throw it away.

Two formulas are included, one similar to ABC and one a variant on PMK.

    Anyone try them yet?
    I don't have access to this issue of PV. Would anyone be so kind as to post the formulae for the developers?
