Extreme sports: Vortex Diving (Jacob Cockle's last piece)
Cornwall, UK, 2013: This (rather long) clip features some fascinating footage of the last "piece" that the infamous vortex diver Jacob Cockle (aka whirlpoolhitman) has been playing with and recording himself in the water as he "dances" with a huge vortex in the Carnsew Pool in the Hayle Estuary. Jacob Cockle died later at this location, the video-footage was first confiscated by the police but later given back to the family of Jacob.
You can tell that this man gotta have been a bit nuts from the first moment of the clip where you only see the huge vortex itself, but things get totally crazy when Jacob plays and "dances" with the vortex underwater and literally "surfs" over the most dangerous areas later in (skip to ~ 22 minutes), wearing a rubber horse head.
R.I.P. Jacob Cockle.
