THE BLUE HOLE

An amazing natural patch int the Egiptian sea

The blue hole is a submarine skinhode situted in Egiptian sea. It's about 100 meters deep. All the bests divers prove to swim down to the bottom but, some of them lose their lives in the attempt. For getting to the bottom, divers need to fill teir air bottle with gas mixtures, wich change the size deppending on the deepth, so it's very dangerous. But it isn't the only problem, because it has seccundary effects, like for example, it makes in you allucinations like  drug. In the bottom of this deep hole there are some cropses of unfortunante divers.
In my opinion it's a bit cray do it, and it isn't a beautifull hole. I don't understand the reason who encorauges the divers. Maybe adrenaline is the reason.
