Don't look down: A guest swims in the infinity pool of the Skypark that tops the Marina Bay Sands hotel towers - 55 stories over the city of Singapore yesterdayHe'll definitely want to make sure he doesn't swim too close to the edge.
This man is the first lap swimmer in the world to enjoy such a view - 55 stories over the city of Singapore.
The £4billion Marina Bay Sands tourism development opened in the city yesterday, and the 150-metre long pool - three times the length of an Olympic swimming pool - was a highlight.
To infinity... and beyond! The pool stretches 150 metres, three times the length of an Olympic swimming pool

In reality, the edge of the pool is usually about an inch below the water level. The water therefore spills over the edge into a catchment below, and is then pumped back into the pool.
The concept is said to have been inspired by the terraced rice paddies in Bali, Indonesia.
They are often seen in luxury resorts such as the Marina Bay Sands.

The resort is set to employ 10,000 people directly and generate up to £48million each year. Entrance to the casino alone is nearly £50 a day - but an average of 25,000 people have visited the casino daily since its initial phased opening two months ago.
Thomas Arasi, president and chief executive officer of the resort, said he expects to attract an astonishing 70,000 visitors a day, 18 million a year.
The resort was designed by Moshe Safdie, who said he based it on a deck of cards.

Last night, singing legend Diana Ross performed for 2,500 VIPs in the resort's Grand Ballroom. Singer Kelly Rowland also headlined an outdoor concert there yesterday.
The opening celebrations also featured a death-defying relay. Seven teams of three participants each scaled the three towers in succession before sprinting across the 340-metre long Sands SkyPark, where the infinity pool is located, to the finish line.
