The exhibition aims to explore the theme of milk as a creative principle and wants to reflect on the meaning of this food as a first nutrient source for man. For this reason, the project takes the form of an artificial galaxy able to welcome visitors of Expo 2015 in a mysterious environment that is necessary to explore step by step, an interactive experience that is transformed during the time of the visit. The project employs translucent surfaces to design an immaterial, fluid and continuous exhibition space. The pavilion is transfigured into a cavity formed by overlying layers of organic semi-transparent membranes that fold back on themselves following curvilinear geometries in order to expand the vertical surface and thicken the exhibition space. At the same time the path of the exhibition is divided into several thematic areas that facilitate the reading of the space and the different contents of the communication. The aim is to maximize the visitor experience, interaction and entertainment, as the experiential dimension is conveyed primarily by the same architectural design.
