Baleen whales have two blowholes, while toothed whales have only one. For this reason, baleen whales sometimes produce a V-shaped spout. The resulting pressure differences between the exhalation of the different species must be taken into consideration for the purpose of making a fountain. A spout is not a typical fountain jet either: it is produced by powerful exhalation, during which lower external pressure and a cooler external temperature cause the moisture in the exhaled air to condense and make it visible as a fountain of mist. The blue whale, the largest mammal on this planet, can produce spouts of up to 12 metres.
This fountain includes a basin with additional water storage, a set of nozzles and pumps to generate adequate pressure. Depending on the design, there are additional interactive elements that allow visitors to choose particular fountains to activate. Lighting can be added to allow for night-time viewing. Many variants are conceivable and will be made to measure for customers.
