Onion Pinch is a cork installation commissioned by the design Biennal Experimenta a Babies and Adult Rest Station designed for the Cais du Sodre Lisbon Subway Station. By approaching the project we wanted to create a space having the capacity to transform, by its physicality, the life in a subway station. We wanted to identify a design concept and a very simple construction technique. We wanted to create an intimate relation between material properties and user's physicality. Cork is very flexible. Flexibility means elasticity and vibration. Thanks to its flexibility, it was possible to shape the cork. The onion rings were realized with different cork types and thicknesses. The installation was articulated in a series of internal paths in which babies could run, walk, climb, lay and rock. The tracks were articulated by the opening or closing of the profiles. The unique parameter, 'position on the Z axis of the bolt', affected another condition of the rings: the flexibility or level of vibration. When installed in the subway the Onion installation immediately became an urban toy. The presence of an extremely alive object, with its texture, with the oscillation of the Onion rings, transformed an unfamiliar, cold space like the subway station into a lively oasis. Onion Pinch has been featured at the show Minimaousse 4 at the Paris Museum Cite' de l'Architecture et du Patrimoine. Project: Caterina Tiazzoldi and Eduardo Benamor Duarte; Team: T. Branquinho, L.
