Guillaume Nery, a french free diver, jumped into the largest sinkhole on Earth with no scuba gear at all. Just a pair of massive, rock hard cojones. Usually when a person sees a huge black whole underwater their first intuition is to get the hell out of dodge. But this guy jumps in head first like he’s Superman or Spiderman lol! The huge sinkhole is called “Dean’s Blue Hole“, it’s a 663-ft deep sinkhole in the Bahamas.
