Look at the regular icicles hanging from the ropes. For the bottom rope, why are the icicle ends in a horizontal line, as opposed to say, the shape of a catenary, the natural form taken by a rope suspended by its ends? I note the ice build up on top of this second rope... but I do not know the answer to my question. Perhaps I shall play "stump the physicist". I wonder if it's like isostasy. Hmmm....
