Poltergeist. Russia

Recently, an incomprehensible thing happened in one of the Sverdlovsk apartments. A strange pattern suddenly appeared on the windowsill: a circle with a symbol enclosed in it, similar to a maple leaf. About three dozen rays radiated from the circle. There was a strange shading between some of them. The drawing was not washed off with hot water or even alcohol.

Numerous friends at home wondered about the origin and meaning of the strange drawing. Naturally, they sinned against mysterious aliens, poltergeists, and cosmic and other radiation. They argued for more than a week, until one of the women caught the eye of an ordinary hot water bottle, which a young mother usually put under her daughter's legs. The only miracle turned out to be that the drawing tightly "moved" from the heating pad to the paint, you can't etch it.

What I liked most about this story was that the owners of the "miracle" were looking for a realistic explanation of what happened until the last minute.
