Biggest Swimming Pool
This swimming pool in Algarrobo, Chile is about 1 kilometer in length and contains 250 000 tons of sea water. Fernando Fischmann, owner of the San Alfonso del Mar resort where this pool was built, now offers anyone to beat his own record. His company Crystal Lagoons can build a similar lagoon anywhere on Earth for just about $350 000 per hectare.
