In the Estonian village of Tuhala, there is a very special well. When there’s a heavy rain, the well starts starts spouting water! The well just so happens to be placed directly over an underground river. After rain water floods the river, water pressure builds to the point that it comes shooting up out of the well, sometimes ½ a meter high! That’s a foot or two, for my Americans. The Tuhala well will continue flowing for a few days after a downpour; during this time, more than 100 liters of water can flow out every second (that’s over 25 gallons per second).
The local legend is that the witches of Tuhala gather in the sauna underground and beats each other vigorously with birch branches causing water to pour out on the surface. They call it the Witch’s Well.
