Have a look at this diving pool just outside Venice.
Takes 2 minutes to plumb the depths.
Only for serious free-divers.
The project was designed by architect Emanuele Boaretto and the Boaretto Hotel Group and opened in June 2014.
Guillaume Nery can be seen sinking at a rapid speed until he makes it to the bottom of the 130ft deep Y-40 Deep Joy pool, after around two minutes of plummeting. The record breaking diver had to empty his lungs to be less buoyant and sink more freely.
