This stone is hanging in front of the door of a family in Buetzow.
It is said it can make weather reports:

"The weather stone of Buetzow

If you can not see it, there is a thick fog;
If it has a shadow, the sun is shining;
If it is wet, it is raining;
If it is white, it is snowing;
If it hangs in water, there is a flood;
If it is moving on the line, there is a storm;
If it points up to the sky, it is the end of the world;
If it is gone, it must be stolen...."
