    Question:



    The water is somehow on the inside of the insulated part. There's no visible cracks in the thing. How did the water get in there and how do I get it out?

    It's one of my lidded mugs. It's double-walled for insulation.

    Did you have the mug cooled?

    Air has a varying capacity to carry water. The hotter it is, the more water it can carry (to a certain max). So if you cooled the mug, there's a chance that water will precipitate, I guess, because the air in there is at its maximum water capacity.

    Not a physicist here, but I think it makes sense.

    ı have this half liter water bottle in the freezer . ı will take it with me to the city tomorrow . Not particularly necessary in late August , but it is all ice and ı wrap with a newspaper page and put it in a plastic bag and the lid is tightly closed and as mentioned it will be wet allover as the ice inside the bottle melts . Obviously not exactly relevant but heat can pass through stuff , ı guess .

    Yep that should be it. In a high end insulated flask you'd have a vacuum in between the walls. That vessel looks like a cheap one so I doubt the manufacturer went to the trouble to pull a vacuum between the walls. Just fill it with air does the trick as well, is less efficient and much cheaper. Naturally the air has some water in it, leading back to Js correct reasoning about the condensation.

    There might just be a tiny leak between the two layers through which moisture could get in.

    I'd say the seal was cracked in some part. Probably too small of a crack for you to easily pick out by eye. As it warms and cools air is drawn in. That accumulates droplets.

    The same thing can happen in double pained windows if they get old or damaged.

    I think I got the mug at Dollarama. I have put it in the fridge sometimes when I wanted to keep a drink cool while I was out but not recently.

    It's likely not a good enough quality to last all that long without deterioration.

    In 2001 A friend and I did a side trip to the Cardiff Giant on a business trip to NE. It is in Cooperstown NY. We've been to the Vermont side of Lake Champlain (Burlington VT). The Adirondacks Mountains are popular as a hiking and camping destination.

    I was also in Cooperstown in 2001. Never heard of that giant fellow however. :D My main memory of the place is everything is overpriced, the food is awful, and parking is tricky.

    The Cardiff Giant is the inspiration behind The Simpsons episode "Lisa the Skeptic".

    Long time ago I worked a week or so as temp labor in a company making double paned windows.
    Part of the production process was filling the hollow alumin distance holders with dry silical gel balls just before these distance holders were used in the next step where they were sealed with silicon rubber into the raw double paned window.
    (one pane on the table... distance holders at the edges on the pane... other pane on top... silicon on the outside of the distance holders also glueing the panes together)
    I worked for that in a small room at 40 C with the air ofc completely dry. Two hours there and two hours other work to recover.

    I think if you have not much money, you can as well refill partially with dried silica gel balls.

    EDIT
    I guess you can re-use the silica balls by putting them in a furnace at 200 C or so for a while to get the water out, whereby I would start a while at 90 C or so and then increase to above 100 C.

    If I am not mistaken the same silica balls are also used in fluidised bed furnaces at much higher temperatures than 200 C.

    what the hell is going on in the United States? I saw a video of a truck with a big American flag running over a bunch of people and spraying something out the windows.
