Delusion
As Wuhne or Wune is called a beaten into the ice hole - usually to fish from or to a manhole to get for divers. In Russia and Finland , Wuhnen are also beaten for ice swimmers.
In addition, a channel that is knocked into the pack ice around a frozen ship so that it is not crushed by the ice is called a Wuhne.
When the entire ice surface contracts on cold nights during a freezing sea on Lake Constance , stress cracks form in the ice. The lake is open between the separate ice surfaces. These cracks, which are often kilometers long, are called Wunen (also Wunnen).
Waken as natural holes in the ice are to be distinguished from Wuhnen . The main difference lies in the thickness of the ice at the edges of the hole: While the edges of the ice on a Wuhne are just as strong as on the rest of the water (so that you can free yourself from them by propping up, for example), the edges of the ice on Waken are significantly thinner and in the Usually brittle.
