"If you're the sort of person who immediately wants to know what the craziest goddamned thing you can do to a 600-foot ocean bottom sinkhole is, world free diving champion Guillaume Nery has you covered. He stood on the edge of the world's deepest blue hole without any sort of breathing apparatus, ignored every fiber of his being telling him he was perched on the mouth of a sarlacc and decided he ...wanted to touch the drain in the ocean's deep end.
And it only gets eerier inside the hole, where you're forced to face the reality that you've stumbled into either a) the lair of something terrible that is going to swim by overhead and blot out the last trace of sunlight you'll ever see or b) the stomach of some sort of ocean bottom Venus flytrap designed specifically to trap and digest people who see something beautiful and feel the desire to swim down its throat."
