this amazing video was made by the french free-diver specialised in constant weight free-diving
guillaume nery (who broke the world record on july 3, 2008 when he dove to 113 meters) and juli gautier.
the video was filmed at the dean's blue hole (the world's second deepest blue hole 202 meters) with a canon 5d mark II and edited by them as well in which both are holding
their breath all the time.
how can one not take a breath for such a long time?
