As infinity pools go, this particular one takes the concept right to the edge. 55 floors above the streets of Singapore, the pool at the city's newest resort - the £4billion Marina Bay Sands - is open for business.

Infinity pools are designed to make it seem as though the water extends to the horizon. 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.
'In Singapore, Marina Bay Sands will be the pivot point in which tourism here is going to explode,' gaming tycoon Sheldon Adelson, chairman of Las Vegas Sands Corp, the parent company of the resort, said at its opening celebration yesterday.

The enormous hotel, which dominates the Singapore skyline, has 2,560 rooms and suites, a fleet of celebrity chef restaurants, shopping areas, theatres, a museum, a casino and a crystal pavilion.
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.

It was due to open in 2009, but was delayed thanks to labour and material shortages, and funding problems due to the global financial crisis.
During the inagural, singing legend Diana Ross performed for 2,500 VIPs in the resort's Grand Ballroom. Singer Kelly Rowland also headlined an outdoor concert there.
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.
