Now that the miners and the rescuers are all above earth and accounted for, Chile is left with a really famous, really deep, really big hole in the ground already equipped with a tiny, risky way to get in and out. It seems a shame to just walk away from it so I've got some suggestions:
1. Turn it into a prison.
2. Turn it into a theme type, expensive, hotel. Luggage would be limited, or course, to small carry on type items.
3. Use it as the home base for a reality show involving people trapped underground who at first think they are going to die and then wait for a rescue.
4. Bring back Fear Factor and film it exclusively down in that hole.
5. Conduct guided tours through it much like Alcatraz Island.
Of course, one never knows, I suspect, when the Phoenix rescue capsule will give out and fall forever into the hole. The risk will probably just make whatever the hole is used for all the more attractive.
Of course, things will have to move quickly on account of our limited attention spans which, now that the rescues are complete, have returned to no more than fifteen minutes on the same subject.
