Come for the burning cup, stay for the esoteric steam knowledge!

    I would have thought the cup would burn up. Didn't think the water would move fast enough to carry the heat away.

    Well, my old boss used to say you can't burn up a boiler section if it has water on the other side. Guess he was right

    Nice! Next trick, throw some sediment in the cup, with water and try it again! Will heat transfer be slowed enough for the cup to burn??? o:)

    In grade school we boiled water in a brown paper bag. The little flap underneath burned right off, but the rest of the bag held fine, until the heat finally got to the part of the bag without water in it and burned it off.
    Paper bags are so flimsy any more that it would be an interesting experiment to see if they lasted as long in the fire.

    Thanks, Gordo. This reminds me of something I did during my seminar days. To show the different heat-transfer capabilities of air and water, I would have two party balloons. One held air and the other held water. I touched the tip of the Bic lighter to the one with the air and it did what you would expect. Then I did the same to the one with the water. The balloon would turn black but never burn. I stood there with the flame to it for quite a few minutes and talked about how water is always better for moving heat from one place to another, and how marvelous hydronics is. It always resulted in a roomful of nodding heads.
    Retired and loving it.

    I did this 30 years ago with an oxyacetylene torch. A torch that melts steel like butter. All it did was scorch the paper and turn it into burnt paper, but it never leaked. The water boiled the heat away as fast as 6000F applied.
