13. Door To Hell - Turkmenistan
http://www.youtube.com/watch?v=ra_a1weqTYQ With a name like this, you know the Door to Hell is going to have a bizarre story. The Door to Hell is a natural gas field in Turkmenistan and the site on which it is located was discovered by scientists in 1971 who thought it was a good place for natural gas reserves. But when the rig gave way, the scientists feared that the gas would spread and cause huge danger to people nearby. In order to prevent this from happening they tried to burn the hole with the hope that the fire would die down in a couple of hours, but things didn't exactly go to plan... Over 40 years later, the fire is still burning and has become a huge tourist attraction. In recent years, Turkmenistan's president has ordered the hole to be closed and the area to be cleaned up but as of yet no process has commenced to close the burning Door to Hell. On top of this weird phenomenon, the Door to Hell attracts thousands of spiders, but scientists are baffled as to why. If a burning hole of fire wasn't enough to put you off then maybe that will!
