A diver is seen in the deepest pool in the world with 45.5-metre (150-foot) located in Mszczonow about 50 km from Warsaw, November 21, 2020. - The complex, named Deepspot, even includes a small wreck for scuba and free divers to explore. It has 8,000 cubic metres of water -- more than 20 times the amount in an ordinary 25-metre pool. (Photo by Wojtek RADWANSKI / AFP) (Photo by WOJTEK RADWANSKI/AFP via Getty Images)
