Sure you can do that deep scuba dive in 47 degree Fahrenheit water off the California coast. Sure you might get to see some kelp, marine life, and spectacular rock formations, but 47 is just 15 degrees from freezing. Why not dive indoors in a balmy 86 degrees? Ahh, but you wondering how you can get a deep dive in a 10 feet deep swimming pool?
Make way for Nemo 33 in Uccle, Belgium, the deepest pool in the world. 108 feet to be exact with “two large flat-bottomed areas at depth levels of 5 m (16 ft) and 10 m (32 ft)”. A circular pit allows you to visit Davy Jone’s Locker. There is also multiple “caves” you can explore. The pool holds 2.5 million liters of non-chlorinated spring water. Every other week the water is lime-flavored and bubbly as well. And with 2.5 million liters of water that will surely dilute out the urine.
