These guys take a pot of boiling water and throw it in the 45 below air. Pretty sweet to see the state change instantly like that.

  • My theory...

    would be that boiling water has microscopic air bubbles which would allow the cold to penetrate the water much more quickly. Just a thought.

  • Been proven!

    I thought it to be a myth too, that is, until i poured hot water onto a cold steel railing and saw it froze before running onto the ground, then tried it with cold water which ran down onto the ground leaving very little frozen to the railing. wouldn't have believed it had I not witnessed it firsthand. Any takers on explaining this one????

  • That's pretty cool

    That's pretty cool. -45 degrees Celcius or Farenheit?

  • beautiful

    you should throw it from much a much higher place or use something to spray it so that the water is divided into smaller drops that have less surface area and freeze better

  • this is normal

    boiling water turns into ice five times as fast as normal water in subzero temperature

    • That is an old myth that has been dispro...

      At some point, the boiling water must reach the same temperature as the "normal" water. Are you saying that a change in temperature carries a momentum?
      Think!

    • u think

      ITS CALLED THE MPEMBA EFFECT introduced in 1969. and it proves tht boiling water freezes faster than cold water. look it up

    • I just read 6 articles on the mpemba eff...

      It is a real, uncommon, and surprising, effect that only occurs under special circumstances.
      It is NOT momentum, gondiggn.
      It is not, under ANY circumstances, 5 times faster than cool water, tulltzter.
      A science proffessor disproved it to our class many years ago but, apparently, he didn't control for the special factors that allow for the mpemba effect.
      But, none-the-less, thanks for the info, tullzter, I learned something from you today.

    • Yes, Hot water freezes faster that cold ...

      Momentum pretty much somes it up, hot water molecules pick up speed as they drop in temperature. You can try this by filling 1 ice cube tray with very hot water and the other with cold water, put them in the freezer at the same time and see for yourself. Watched some science guy explain it on Discovery Channel.

    • That is utter nonsense!

      Heat is simply a measure of the activity in molecules. If they were "picking up speed", they would be getting hotter, not colder. The reason this water freezes quickly, is that it is thrown, thus making lots of little bits of water, each of which will freeze quickly.

  • The real truth

    This was dealt with on a science podcast recently. A tray of ice cubes made with boiling water WILL freeze more quickly than a tray made with cold water. The reason is due to evaporation, not "speeding molecules" or other such sillyness. Because the water is boiling, some of the water is escaping into the air...LEAVING the tray. Because of this there is less water in the tray to freeze. If you were to measure the volume of the water in both trays so that it was precisely the same in each tray before freezing...and then measure the exact volume after the trays were frozen, you would find less water in the tray where the water had been boiling. If you put enough water into the tray with boiling water so that the frozen measurement would be the same, it would require more boiling water and the amount of time required to freeze the trays would be exactly the same.
