A gent (whose real name I can't map to a Cellar userid, but thanks) suggested this item, which was Farked but deserves further attention anyway. An Alaskan guy started building an ice sculpture by turning on a sprinkler and leaving it on. With further sprinkler adjustment as needed, over 5 months the tower of ice was over
150 feet high.
full story a week ago
Here it is with a guy climbing on it so you can get the scope of it:
But before I could get to posting the image, a few days ago the tower collapsed!
colorful web site for the whole thing with many pics
I love this project, and I hope to be able to try my own version one winter.
