A video shared a unique natural phenomenon in a village called Dino?a, located in southeastern Montenegro—a small country on the Adriatic coast. There is a mulberry tree standing in the meadow there that turns into a fountain whenever it rains heavily. From a hollow in the tree trunk,water can be seen gushing abundantly.

Apparently, rain had flooded the underground springs and the additional pressure created pushed water up the tree trunk through the cracks or hollows in the trunk, until it poured out of a hole a few feet above the ground. As you can see from the video, the ground is quite sloppy indicating the amount of groundwater there is in the soil and below. You can also see water gurgling out of other holes in the meadow. The entire area is flowing like a small stream.

According to a local man interviewed,this has been happening for the last 20 to 25 years or perhaps even longer. He estimates the tree is 100 to 150 years old.

While Montenegro's tree fountain is indeed unique, it isn't the only example of water gushing out of the ground after rain.In the Estonian Village of Tuhala, there is a well that starts spouting water after a heavy downpour. The well happens to be placed just over an underground river.After rain water floods the river, water pressure builds to the point that it shoots up out of the well, sometimes up to half a meter high. This continues for a few days.During this time, more than 100 liters of water can flow out every second.
