You can carry 2.5kg of dry ice in your hand luggage if you talk to the air carrier beforehand. When I found that out, I was amazed nothing like this has happene

  "Though someone told me they took a bottle full of frozen water and got through, since it isn't a liqid by the rules.. go figure." Maybe in the really early days of the liquids ban, but these days they're a lot more up to speed on elemental phases.

    That is completely irrational that airport security would consider banning frozen water some kind of improvement in their performance. A liquid explosive would have a freezing point way below that of water. The freezing point of toluene is too low to be practical for anyone to carry a frozen lump of it. Frozen water would be obviously water and obviously harmless.

  I wonder if you deliberately did this: http://www.salon.com/2002/10/03/askthepilot13/ http://www.salon.com/2002/10/03/askthepilot13/ whether it would be considered terrorism.

  This, probably by accident, makes sense. The liquids they are trying to prevent (acetone among them I think) can't be carried around frozen.

  Yet, you cannot take a small bottle of water That's true, of course. You can nevertheless avoid paying 8 bucks for a small bottle of water after security: Take empty bottles and fill them up in the loo after the security check.

    Water quality and temperature is often an issue. And on some airports, there's an additional security check before boarding – for example sometimes in Male.

    I always take an empty water bottle with me. I always travel with a water bottle, even on short (hour long) car rides. Usually a drinking fountain is provided outside the bathrooms. Better yet, find a restaurant with a soda fountain, those always have a water dispenser on them, and you can add ice too. Just enter and let the staff know you are filling up your water bottle, they won't mind.

      And now you've just circumvented aircraft security smuggling dangerous, dangerous water on-board.

        Water isn't the issue, explosives or components thereof are, as well as not having to individually check the contents of millions of bottles every day. You'd have a point if airport restaurants commonly sold nitroglycerine. Which they don't.

  "(Though someone told me they took a bottle full of frozen water and got through, since it isn't a liqid by the rules.. go figure.)" This is the problem...the rules are not clear and randomly enforced and enforced differently at each airport. At O'Hare in Chicago, my wife had to throw out her applesauce that was sealed because it was over 3oz. The agent said that if she had opened it and eaten a bit then it would've been fine but he wouldn't let her do that there, so her snack was thrown out. So they are saying it would be ok to tamper with the product but when it is sealed then that can be a threat. The logic, or lack thereof, behind the decisions really boggles my mind.
