Submerged Cliff Diving

This incredible video of Gillaume Nery jumping into the world's largest underwater hole will actually make you hold your breath. The champion free diver dives into this giant black hole holding his breath the entire time.

I had to watch this video on repeat in order to fully be able to grasp how crazy this is. The man jumps into this frighteningly dark, deep hole without an air tank! I suggest watching Gillaume Nery's dive at least twice -- the man is absolutely insane!
