Trippy video of a free dive to the bottom of the worlds deepest blue hole.
I think that might have been the wrong link.
Nope.
I was picturing a computer generated free fall into a deep part of the ocean.
Haha nope, blue holes are kind of like sink holes in the ocean, they are just voids that go straight down, in that ones case 300ft or so. Its trippy to see a guy just dive into one to the bottom and then climb out all on a single breath of air.
