Created by artist Leandro Wrlich, this optical illusion is one of three installations at the Museum of Art in Kanazawa, Japan. Erlich put two clear acrylic glasses about a foot apart and filled the space between them with water. The top surface is also filled with five inches of water to give it the effect of a real swimming pool.
Known as China's Dead Sea, this local swimming pool in Daying County, Sichuan is believed to be China's largest indoor water park and is a 30,000 square-metre salt lake, meaning swimmers float freely on the surface, just like the Middle East's Dead Sea. We're not quite sure why everyone needs rubber rings though!
Got a head for heights? You'll need one if you're thinking of swimming in the rooftop pool at the Marina Bay Sands hotel in Singapore, as the infinity pool is 55 storeys up (665ft, 202 metres above ground)! It's three times the length of an Olympic swimming pool and also claims to be the largest outdoor pool at this height.
The newly opened Badboot (which means 'bathboat') in the Port of Antwerp, Belgium is the biggest floating swimming pool in the world and was built on a shipyard in the Netherlands before being towed over the water towards Antwerp. The pool floats on the water and is 120 metres long. It comes with a restaurant, lounge bar and a children's pool.
You'll need a real head for heights if you want to take a swim in the new pool at the Holiday Inn Shanghai Pudong Kangqiao in China. The pool, which is located on the 24th floor, extends over the side of the building and is transparent giving swimmers a stomach churning view to the ground far below. A spokesman for the hotel says: 'It needs some courage to swim to the other end.'
It may just look like a regular swimming pool at a hotel or someone's back garden but what you see is in fact the rooftop pool at Singapore's Changi International Airport. The pool overlooking the runway is the ultimate way to spend the, let's face it, tedious time waiting for your plane to leave at the airport. Just don't get too comfortable and miss your flight!
At the Jianqiao Beach Resort in northern China's Shandong Province there is a large pool filled with jelly-like beads of aloe that you can swim in before you take a dip in the sea. The reason? The resort says the jelly bath could form a protective layer on humans against ultraviolet rays and sea water irritation. We're just excited about it being a pink pool!
As far as natural swimming pools go, Cenote Dzitnup in the Yucatan, Mexico is pretty weird and awesome. To get to it visitors descend through a cramped tunnel into a massive cave where the turquoise blue pool glows under a shaft of light from a hole in the ceiling. The only catch is that the water is ice cold so you might want to swim in your thermals!
We love the Badeschiff (bathing ship) in Berlin, which is located on the Spree River and allows people to swim near the river, which is too polluted for safe bathing. The swimming pool is heated in the winter and has a roof, plus a sauna world! Who said you couldn't enjoy outdoor swimming in winter?
Ever wondered where you can find the world's biggest hotel pool? The San Alfonso Del Mar Resort in Chile is home to this gigantic swimming pool filled with 66 million gallons of salt water that stretches right across the coastline. It's not just for swimming either, as you can sail and windsurf on it too.
