If it’s being done big…it’s apparently being done in Dubai.
The world’s deepest swimming pool has been officially opened. Deep Dive Dubai is 180-feet deep and holds 14 million liters of water…which is equal to six Olympic-sized pools. That's over 15-stories... deep!
And check this out... those who dive its depths will find a “sunken city,” featuring an “abandoned streetscape with an apartment, garage, arcade, and a functioning foosball table.”
