A group of German scuba divers are claiming a new world record after playing the same card game undersea for 36 hours.
The 16 divers who worked in shifts so they could modify oxygen tanks sat on the bottom of a pool in Geiselhoering, playing a traditional Bavarian card game called 'Sheep's head'.
Organiser Eric Schlegelmilch said: "We gave up counting who owed what after an hour. We didn't want anyone going tummy up."
Now the group decided to contact Guinness World Records officials with a video record of their stunt.
