Oxymoron? I think not. If you are a follower of the Zap, this is even crazier than the top 10 jump videos I posted a few months ago.
Guillaume Nery is a freediver, meaning he dives to great depths without any scuba or fins. This man heads over 600 feet down in this video.
It is almost an optical illlusion as he stands on the edge of an underwater sink hole and jumps 600 feet underwater to the bottom.
