WATCH: Is this sky-high swim the world's coolest pool?

Fancy a sky-high swimming pool? This one sits 57 stories above the city of Singapore.

The Marina Bay Sands boasts the world's largest rooftop infinity pool... and one of the greatest selfie spots in Southeast Asia.

You need to be a guest at the hotel to swim here, but don't worry, there is a Plan B - the observation deck is open to all (tickets from SGD23/€14 at marinabaysands.com).

Cocktails, anyone?
