Death defying diver David Calvo has just pulled off a Jaws-dropping stunt – solving two Rubik´s cubes sharing a tank with six sharks.

David, 24, completed the puzzles in just 76 seconds as he sat on the bottom of the tank at the Terra Natura Park in Benidorm, Spain.

The former national Rubik cube champ for Spain, he solved both puzzles one-handed at the same time. “He was fast – but he did have a bit of an incentive from our sharks. They´ve never eaten a man – yet – but you certainly wouldn´t want to linger,” said one keeper.

The 24-year-old has managed to beat his own record set last April on an Italian TV show where he solved two cubes in the water, but without the sharks. He added: “I found I was very focused on getting it done as quickly as possible – I wasn´t very keen on hanging around.”
