Unusual well

An unusual well is in the village of Pokrovskoye, Mykolayiv region of Ukraine. Deep, always filled with tasty cold water, the well at times with such force draws in itself air, that it is necessary to exert uncommon force to open the lid. Sometimes, on the contrary, he pushes the air with such force that the lid on it seems to be feverish, and she jumps all the time, like on a boiling kettle. If you throw a hat into such an extraordinary well, it will be thrown out with force!

The local population has long used this extraordinary well as... "a kind of barometer" for guessing the weather. It turns out that there is a certain pattern in the "behavior" of the well: it "breathes" the air always before good weather, but exhales before rain or snow. Scientists explain this phenomenon by the peculiarities of the soil structure. The fact is that in the Black Sea regions of Ukraine there are powerful strata of limestone. In the Mykolaiv region they come almost to the surface, that is, they are located above groundwater. During good weather, atmospheric pressure rises, and these layers, which have many voids, are filled with air that is drawn into it. Before the rain or snow atmospheric pressure always falls, then the reverse process occurs: air from the limestone layers comes to the surface.

Of course, the unusual well in Pokrovsky is not the only one. Similar wells-barometers are found in the southern regions of the Kherson, Zaporozhye and Odessa regions, and also in Kazakhstan on the Ustyurt plateau. The local population uses them as reliable precursors of the weather.

But however, the original "guess" the weather not only mentioned extraordinary wells, and some rocks. One of them is in the Khabarovsk Territory. This is the rock of Bakhalaz. It is known that before the onset of rain, it... "cries": on the rock appear large drops of water. You probably guessed that, similar to the walls of the barometer wells, the rock of Bakhalaz consists of porous rocks, which first absorb moisture from the air, and then the surplus is extracted as "tears".
