A gigantic twelve-metre-high salt igloo serves as a container for all kinds of traditional and state-of-the-art solutions to thirst everywhere. These are the foundations of one of the most imposing thematic places, which also surprises because it guarantees a pleasant temperature without air conditioning thanks to its particular design. The metal skeleton, so chosen to avoid future demolition, supports three superimposed layers of ETFE, a material similar to Teflon. which also serves as an inflatable vault, crusted with salt by a timed brine system. Inside, five differentiated spaces change their appearance thanks to a complex machinery of lights. The visitor can see and feel the complete water cycle in one of the rooms, where clouds, rain and evaporation of water can be found, all in a 'hydroponic' garden. During the tour you can compare the excessive use of water in the cities with its rational use in the desert, learn about the migrations in search of this resource or the artefacts created for its collection. A marvel not to be missed.
