Guillaume Nery of France completed the unbelievable, free-diving 40 metres to the bottom of the world's deepest pool in one single breath.
The diver emptied his lungs of air before beginning his descent in the Y-40 Deep Joy Pool. Doing this reduces his buoyancy, meaning he can sink faster.
The 35-year old, who has previously broken four world records in free-diving, spoke about the experience of being underwater; he said: "It is like I am out in space without gravity.”
The feat whilst garnering widespread social media awareness, isn't a world record by far. In fact, Nery is also capable of diving 126 metres below the surface in a single breath.
The Y-40 Deep Joy Pool is heated between 32-34 degrees C, making it more comfortable for swimmers who like to swim without a wetsuit.
