    Yeah and it reminded me of a demonstration done by Professor Julias Sumner Miller once.
    He boiled water until it froze.

    How you ask?

    He put some water in a petrie dish and covered it with a bell jar.

    Boiling point changes depending on pressure.
    Thats why you have radiator caps in cars.
    They allow the pressure inside to build (to a point) which in turn raises the boiling point, keeping the water from turing to steam.

    The opposite effect is that lowering pressure decreases the boiling point.

    With the bell jar in place he started pumping out the air (lucky there were no freshly roasted coffee beans in there).
    As the pressure reduced the boiling point of the water lowered to the point where room temperature was enough to make it boil.

    Removing the air I think also lowers the ambient temperature (why space is cold?) and at some point it reaches zero.

    So what you saw was the water bubbling away then suddenly freezing solid.

    There seemed to a be a few more interesting videos on that site.
    I might post a few other links.

    TG enters stage left as Chuck Norris, makes a coffee with the EM6910 then leaves quietly, avoiding the mayhem around him. ;)

    Chuck Norris doesnt make coffee with a 6910; the 6910 makes it for him (an undocumented design feature).
