The world's deepest swimming pool is due to open in Poland later this year, promising amazing depths of 45 metres. Yup, the thought of it both impresses and petrifies me in equal measure, too.
DeepSpot - in the central Polish town of Mszczonów, which is about 40 kilometres (25 miles) from the capital Warsaw - will open its doors to the public in autumn, with a water volume equivalent to 27 normal swimming pools.
According to local media, the pool will be 45 metres (148 feet) deep. This means it will be five metres (16 feet) deeper than the present record holder, which is located in the northern Italian town of Montegrotto Terme.
Eight thousand cubic metres of water will be used to fill up DeepSpot, which is the equivalent of 27 normal - i.e. 25-metre-long - swimming pools.
Reportedly constructed by the same company who built the popular indoor skydiving simulator FlySpot in Poland's Warsaw West County, it will include an underwater tunnel, hotel rooms overlooking the pool, as well as restaurants and conference rooms.
And it won't just be for scuba divers, either, as DeepSpot will be accessible to everyone. Well, anyone who's not too afraid of deep water, that is.
However, sadly for the impressive pool, it will only hold the record as the world's deepest for around six months. That's because that's when the Blue Abyss, currently under construction in Colchester in the UK, will open with a 50-metre-deep (164-foot-deep) pool to dethrone it.
The brainchild of ex-forces diving instructor and technology consultant John Vickers, planning for the project began back in September 2014.
Vickers commented: "As Apollo 11 Astronaut, Michael Collins said, 'It's human nature to stretch, to go, to see, to understand. Exploration is not a choice really; it's an imperative.'
"I wanted to push boundaries, to go beyond the expected, to plan for the future, not just for today. This is a huge undertaking, but the reality will be a legacy for generations to come."
According to the Blue Abyss website, the 'unique' aquatic centre will house the largest and deepest indoor pool of its kind globally.
"The pool will have several entrance points and feature multi-stepped depths to accommodate for a variety of activities and simultaneous use, leading down to the 50m shaft," the website explains.
"On one side of the pool, a large table-like area at 12m will be able to house, for example, a mock section of the International Space Station for commercial astronaut training."
I mean, it's always nice to have a choice between which extremely deep swimming pool to go for, isn't it?
