Dive in - Daily water

Aua extrema


Aua extrema means extreme water in Romansh, the Latin-based language spoken in parts of Eastern Switzerland. Everything in this exhibition revolves around water, the element which ensures life and survival on our planet and which is increasingly sought after around the globe. But East Switzerland, whose cantons are sponsoring Aua extrema, has the largest water reserves in the whole of a country which already enjoys an abundance of water. So it is only fitting that you should get your feet wet at this exhibition – have fun!

Barefoot in the world of water

Aua extrema doesn’t just talk about water. This life-giving element stages its own amusing performance in an ankle-deep 1'700-squaremetre water tank on the Neuchâtel platform above the lake. You are asked to take off your shoes and socks when you enter the exhibition. The water has a pleasant temperature and visitors go barefoot through the water forest, find the house of ice flowers, admire the aerial view and relax at the water bar. Water turns out to be the network of networks that links the rivers and streams of East Switzerland with the world's oceans.

Water every day. More water than others

At the same time, Aua extrema enjoys playing with contrasts. The house of ice flowers is a cold spot, even in summer. The ice crystals that grow there disappear at the slightest touch, only to reappear later. Amid the ice flowers, video images remind us of the difficulties involved in searching for water in Mozambique. Having water available every day – something we take for granted – remains an impossible dream in many parts of the world.
