  • Probably not a good idea to handle dry

    ice with your bare hands, whether youre a 'skilled professional' or not.

    • You sure about that?

      > Probably not a good idea to handle dry ice with your bare hands

      Have you ever worked with dry ice yourself? (Also warn everyone against cigarette lighters, since you could easily burn to death or set your house on fire, right?)

      Dry ice is harmless as long as you keep moving. If you let it remain in one spot on your skin, it takes a bit longer than one second before you feel sudden pain and receive an invisibly small blister. It's possible to receive a bigger "burn" from it, if you do stupid things.

      But that's similar to matches or a candle: don't place your skin directly against the dangerous part for many seconds. Neither open flames nor dry ice are toys for little kids.

      Also watch:

    • Great Video

      I'm an instrument tech. for a chemical plant, and we use this method to calibrate temperature transmitters. Its a great way to very quickly achieve subzero temperatures

    • I'd probably still use gloves, but you

      can do anything you like with it.

    • Dry ice is not that cold

      They're about the same as (wet) ice.

    • Low temperature hazard

      If pressed against flesh, dry ice is cold enough to cause tissue damage from frostbite. Ranchers use this for "Freeze Branding" of cattle. (After healing, the returning hair grows back white. I wonder if body-modder people have tried that...)

      -100F chilled alcohol is worse. There's no gas layer as with dry ice, so it freezes flesh instantly. If small droplets drip off your flowers, don't let them hit your skin. Yowch!

    • Freeze branding

      >I wonder if body-modder people have tried that...

      Yes, yes they have. Branding, whether done with extreme heat or cold, is used by body-modders who want something a bit less visible and more striking than a tattoo

    • white hair

      I wasn't clear enough.

      I wonder if they know the trick to producing stripes of white hair. Cryo-brand a shaved spot on your scalp. Become Lily Munster permanently, or make patterns. The brand itself is under hair and mostly invisible.

    • Dry ice is -109 degrees F. or lower.

      That's a whole lot colder than 'wet' ice.

  • Alcohol

    hey sorry what alcohol did he use????

    Isn't it too dangerous to try something like this on your own?

  • Hello

    Back in 1975 I had a school teacher pick up dry ice and move it from one container to another and his hand hit the edge of the table and it shattered both his ring and little finger into tiny shardes.You are an idiot for touching dry ice in any manner without gloves or other safety protection.

  • can u eat it?

    i was wondering if you put a gram cracker or chips or something in it if u can eat it, like normal liquid nitrogen?

  • Definately poor man's liquid nitrogen!

    And this is definately a poor man! Especially regaurding education. Liquid nitrogen is -321 degrees Farenheit or 77 K! This is no where near what was displayed in this lame demonstration. That was about as impressive as if he just placed the items in the freezer. The video was of some comical value though, I laughed out loud watching the idiot throwing cherries around his trailer home! LMAO
