The last pice of the ice wall was placed and glued. The glue we use here, when gluing together ice, is ordinary tap water. You just have to get it really cold before you pour it on, which frankly isn’t very hard up here. We made a big effort to get the walls as ready as possible and get some of the boring job done. One of us also managed to cover the hole camera in slush, which makes it really hard to see the last part of the day.
