The second largest blue hole in the world is in the Bahamas, and people free dive it. Crazy people, people who clearly want to die, and look awesome while doing it. Blue holes are basically underwater sinkholes, like the one we recently saw in Guatemala, associated with rainwater infiltrating bedrock in the Pleistocene era.

This particular Blue Hole is called Dean’s Blue Hole, and is 663 feet straight down, as if it were drilled with a huge drill bit. Guillaume Nery dove it with no tanks, no fins, in a perfectly weighted suit. Not only does he look like a super hero, but he is probably one of the more fearless men I could ever imagine. Well, almost as fearless as Julie Gautier, who filmed the dive, also tankless!

This is a no-no. I couldn’t EVER. First of all swimming in the ocean is sketch. Swimming in water where you can’t see/don’t know where the bottom is makes me so jumpy I can hardly type about it, and most of all, a black hole?! But it does look incredible. Like he’s on another planet in super slow-mo. Take a look:
