ten terrifying swimming pools you could drown in number 10 juyeon waterpark wave pools are a popular feature of water parks around the world they give visitors the chance to enjoy predictable peaks and troughs without needing to go to the beach but the equipment that's needed to create the effect poses some safety challenges sometimes things don't exactly go to plan in July of 2019 people had flocked to the she yeo-eun waterpark in northeast China looking to cool off in the heat the wave pool was full of swimmers and for some reason the machinery malfunctioned and created a wave much bigger than the pool was designed for people were swept away and thrown into the air before crashing down onto tiles amongst all the screams people covered in blood tried to desperately escape the water in case another wave was approaching in total more than 44 people were seriously injured and it was incredibly lucky that no one died in the crush despite accusations that the pool operator was drunk at the time of the incident Park officials revealed a power cut was responsible for the freak wave which means that in the right circumstances it could easily happen again number 9 y40 the deep joy y40 the deep joy in Italy is currently the deepest swimming pool in the world at 130 feet it's as deep as a 14 story building is tall and contains 150 2,000 cubic feet of water it's made up of a traditional pool shape with a cylindrical section that goes deeper beyond it and as you've probably guessed this isn't designed for swimming lengths it's used by scuba divers and free divers and has caves and ledges to explore as well as a viewing tunnel that people can walk through to look out at what's happening in the depths of course with people swimming so deep there's an inherent danger with y40 making one wrong move could easily lead to serious difficulties and anyone who takes a dive has to sign a waiver just in case the worst happens before we move on be sure to subscribe to top

and reaching a depth in parts of 115 feet it contains 66 million gallons of water in the distance from one side to the other is the same as 20 Olympic swimming pools to keep it running water is sucked in and filtered from the ocean and maintenance costs around 3 million dollars a year if the images look surprisingly bereft of people enjoying the water that's because no one is actually allowed to swim in the pool today it's only used for boats and kayaks and you'll soon be chased by security if you jump in this is because there's no way a lifeguard would be able to spot and save anyone that had gotten into difficulty and there are rumors that a young boy drowned there a few years after it had opened number seven chongqing when the weather's particularly hot how desperate would you be to go swimming this was put to the test in 2016 in the city of Chongqing in western China when daytime temperatures reached a sweltering 104 degrees Fahrenheit it seems everyone had the same idea of visiting the local pool and pictures showed just how packed the place became it was virtually impossible to find any space amongst the crowd of people and some people described as looking at dumplings in boiling water there were questions too about the safety of visitors first was the question of pollutants making their way into the water and whether it was possible to adequately treat it the other was what would happen if there was an incident if someone began to drown there was no chance that they could be rescued and if the pool needed to be evacuated it seemed almost inevitable that some people would be crushed in the panic [Music] number 6 the library blood-red pool we're so used to fools beating a certain shape than a color that anything different feels bizarre that's the premise behind the pool at the library resort in Thailand where swimmers can become so disoriented that they find themselves struggling in the water situated on Koh Samui chaweng beach the luxurious minimalist resort had chosen design features that make its pool unlike anything you'll see anywhere else in the world because its water appears to be blood red in color there's nothing different about the water or the way they treat it and the entire effect is created by red tiles that line the pool this does however make it more difficult to see the bottom and it just feels weird swimming here if you ever visit just be careful when you dive in otherwise it could be the last thing you ever do number-5 skellefteå held in February of every year the open Scandinavian winter swimming championship is held in skellefteå Sweden in a contest that challenges the extremes of human endurance that's because the 25 metre pool that they use for the races is cut from two-foot thick ice specifically for the competition and is in a location that's only a hundred miles away from the Arctic Circle temperatures fall to unbearable levels and as soon as you dive in you're faced with a burning sensation all over your skin and your chest cramps up and makes it difficult to breathe you'll fall unconscious after just 15 minutes in the 32 degree fahrenheit water and you would die within an hour if not treated which is why the race organisers have a medical staff divers and lifesavers across the venue there's also a sauna and hot tub next to the pool so participants can quickly warm themselves up to hopefully starve off the onslaught of hypothermia those who swim here swear by the health benefits of swims like this and it's said to help fight off stress depression and insomnia as well as helping lose weight there are serious risks though and if things go wrong your body will shut down because of the cold you lose any ability to escape the water number four the pool of death there are hundreds of stunning places you can take a swim in Hawaii but there's one that's become particularly renowned for the danger it poses a place known as the pool of death it's on the island of Kauai and is a flooded cove on the coast that's made from volcanic rocks the water is perfectly clear so you can see to the bottom and it's the ideal temperature for a relaxing dip but this serene tranquility can soon turn into a nightmare the waves of the ocean that roll up against the rock walls can suddenly increase in intensity and smash against the pool and whoever is in it a large number of people have died here either because they were overwhelmed by the waves and drowned beneath the water or were simply thrown against the rocks with such a force it's one of the most dangerous places to swim in the world but despite knowing the dangers its surroundings still make it a popular destination [Music] number three Nemo 33 until the opening of the y40 pool in Italy Nemo 33 in Belgium had the record for being the deepest in the world reaching a maximum of 113 feet it contains six hundred and sixty thousand gallons of spring water that's heated to a constant temperature of 86 degrees Fahrenheit there are caves that can be explored and you can barely see the bottom from the surface even though it's full of crystal-clear water it's open to tourists amateur divers and professional divers but because of the dangers involved with such a deep pool of water there are strict safety measures to prevent any accidents no one under the age of 12 is allowed there and everyone who dives must have a dive buddy or instructor with them at all times luckily no fatal incidents have ever happened at Nemo 33 but that's only because they're so careful all it would take is one mistake at the bottom of the deep pit and there'd be nothing anyone could do to save you number two Marina Bay Sands the hotels in Singapore are home to some of the world's most amazing swimming pools but the one that stands out above the rest is the infinity pool on the top floor of the Marina Bay Sands Hotel it is the highest pool in the world at an altitude of 1115 feet and swimmers can go right against the side to look out across spectacular views of the city this certainly isn't somewhere to visit if you're scared of heights and it's been known to panic some people because swimming in a place like this feels so unnatural it's also subject to extreme weather conditions when storms pass over the city and if you're in the water when this happens you might struggle to get out without assistance number one the devil's pool the most dangerous pool in the world is one that was formed naturally over thousands of years it seems unbelievable that anyone would willingly choose to go here it's known as The Devil's pool and it can be found at the edge of Victoria Falls in Zambia against the waterfall edge is an area that's perfect for swimming in and that is surrounded by rocks that prevent the flow of water taking you over the side it's an extremely popular tourist spot and one that offers some of the most amazing selfie opportunities anywhere in the world but make one wrong move and it'll all be over sometimes the currents can be enough to drag you underwater and there's also the ever-present risk of falling over the edge of the three hundred and fifty five foot high waterfall there have been several deaths here over the years and there likely to be many more in the future but most who go there feel it's a risk worth taking to be able to swim in such a beautiful place subscribe to top 5s
