Twice a year, between the months of February and March, the Atlantic Ocean waters roll up the Amazon river, in Brazil, generating the longest wave on the Earth. The phenomenon, known as the Pororoca, is caused by the tides of the Atlantic Ocean wich meet the mouth of the river. This tidal bore generates waves up to 12 feet high which can last for over half an hour.

The name "Pororoca" comes from the indigenous Tupi language, where it translates into "great destructive noise". The wave can be heard about 30 minutes before its arrival, and it's so powerful that it can destroy anything, including trees, local houses and all kind of animals.

The wave has become popular with surfers. Since 1999, an annual championship has been held in São Domingos do Capim. However, surfing the Pororoca is especially dangerous, as the water contains a significant amount of debris from the margins of the river (often, entire trees).

ook op deze site; world's largest aquarium!!!

Placed at the lobby of the Radisson SAS Hotel in Berlin, the 25 meters high AquaDom is the largest cylindrical aquarium ever built. Filled with about 900,000 liters of seawater, it contains some 2600 fish of 56 species.

Combined with a vast amount of sandblasted glass, the giant AquaDom gives a transparent-like feeling to the lobby. Guests and visitors are able to travel through the aquarium in a glass-enclosed elevator to reach a sightseeing point and restaurant under the glass roof. Two full-time divers are responsible for the care and feeding of the fish and maintenance of the aquarium.

Some of the interior rooms and suites look out over the atrium, offering "ocean views" of the AquaDom.
