This is the bizarre moment a huge blow hole opened in the middle of the desert – firing sand hundreds of feet into the air.

Workers tried to fill the hole using a digger to push sand into the gap, but to no avail.

But each time they pushed sand into the hole, it immediately threw it back into the air, along with other pieces of debris.

In the video, the men appear to be astounded as they watch the sand flying hundreds of feet towards the sky.

It is believed the clip was recorded in a desert in Saudi Arabia although the exact location remains unclear.

A blowhole is a small opening in the ground through which air will blow out or suck in—a kind of natural fan or vacuum.

The operation of blowholes is tied to weather; air temperature and pressure are the elements that interact to drive this phenomenon.
