There are many mysterious phenomena around the world that never fail to shock us.
One such mystery lies in the Aljof area in the north of Saudi Arabia. There is a mysterious pit here, which has never filled up with sand. The reason behind this is also very strange.
A few years ago a video went viral in which it was claimed that if anything is put into this pit, it sends it back hundreds of feet into the air.
Let us tell you that the entire desert area of Aljof is spread over 1 lakh square kilometers. This place is mostly hot, because it rains very rarely.
It is said that after putting anything in this pit, it gets out. In fact, in desert areas, small holes often form blowholes that are impossible to fill. These blowholes are also called natural vacuums.
According to scientists, blowholes depend on weather, air temperature and pressure. When outside air warms up, it may eventually attain the same density as air underground, causing air flow at the blowhole to stop. When the air outside continues to warm up, it causes air to blow out of the whole.
