The Sands SkyPark in Singapore is an awe-inspiring engineering wonder.
At the top of the 55 storey building is a 150-meter infinity swimming pool.
But swimming to the edge won’t be quite as risky as it looks.
The pools have two circulation systems.
The first functions like that of a regular pool, filtering and heating the water in the main pool.
The second filters the water in the catch basin and returns it to the upper pool.
The infinity pool on the roof of SkyPark spans the three towers of the hotel.
The 4billion hotel makes it the world’s most expensive hotel.
