Making Ice Cream With Liquid Nitrogen

Posted by timothy on from the something-for-the-nothern-hemisphere dept.

JasonMaggini writes "Popular Science has an article on how to whip up a batch of ice cream in 30 seconds or so by using liquid nitrogen. Just the thing for those hot summer days. The article is by Theodore Gray, creator of the ultra-spiffy Periodic Table Table."

    Liquid Nitrogen should be used for cooling heavily overclocked CPU's, and that is it!

    None of this ICE CREAM MAKING... makes it look like its for wussies.

    If you substitute liquid oxygen for the liquid nitrogen you could be having baked alaska in 30 seconds.

      You do realize that this is Slashdot, right? Getting fat is not a problem, it's the general condition.

    I doubt it. A buddy told me about the stuff they used to do at CalTech...

    DISCLAIMER: My buddy may have been shitting me...

    He said they used to freeze frogs in liquid N2 and throw them against the wall to shatter. Then they'd put it in the wastebasket, and get a kick out of the reaction the stink got from the next sucker to enter the room.

    One day, he said, a guy didn't have any N2, so he used LOX instead. It reacted with the volatiles in the frog and blew out the wall when they threw it.

  8. Where does one get liquid nitrogen? by mrsam · · Score: 5, Funny

    The obvious question that I have, immediately after reading this story, is how exactly an average Joe-sixpack goes about obtaining a sufficient quantity of liquid nitrogen?

    This whole thing sounds very interesting, but I don't think I can go into your average supermarket store and ask for some liquid nitrogen:

    "Hello, I'd like a loaf of bread, Cheerios, and a gallon of your best liquid nitrogen. And, uh, a few grams of plutonium. I need it for my flux capacitor."

    1) Take cooler of LNO2
    2) Suspend an ice cube tray full of vodka in it.
    3) Add resulting alcohol cubes to a glass of OJ
    4) Profit!! (or something...)

    The alcohol won't freeze at temperatures designed to make normal ice, but the liquid nitrogen is cold enough to make the liquor freeze. No more worrying about the ice dilluting your drink, as it melts the drink becomes stronger.
