If you fancy a dip in this pool, you'll need a head
for heights - it's 55 storeys up. But swimming to the edge won't be
quite as risky as it looks. While the water in the infinity pool seems
to end in a sheer drop, it actually spills into a catchment area where
it is pumped back into the main pool. At three times the length of an
Olympic pool and 650ft up, it is the largest outdoor pool in the world
at that height. It features in the impressive, boat-shaped 'SkyPark'
perched atop the three towers that make up the world's most expensive
hotel, the £4billion Marina Bay Sands development in Singapore.
