In the year 1971, Soviet engineers set fire to a gas-filled hole in the Turkmenistan desert, thinking it would burn out in a few days.

However, to their astonishment, the flames have persisted, and the site, known as "The Door to Hell," has been burning continuously for over 52 years

Hundreds of natural gas fires illuminate the floor and rim of the crater. The crater has been burning since the 1980s. How the crater formed is unknown, but engineers ignited the crater to prevent poisonous gases from spreading.

In England you sometimes see these "wavy" brick fences.

And curious as it may seem, this shape uses FEWER bricks than a straight wall. A straight wall needs at least two layers of bricks to make is sturdy, but the wavy wall is fine thanks to the arch support provided by the waves.

The Skeleton of Turtle.

Its shell is made up of about 60 bones that include portions of the backbone and the ribs, meaning the turtle cannot crawl out of its shell.
