Dutch designer Martijntje Cornelia is the author of tasty rings collections in resin and cotton candy that she sells on her shop Etsy. The sugar is a moving material that oxidizes and changes of the shape with time. To become solid, Cornelia exposes the cloudy sugar in parks or in suspension on bridges, like public installations. She waits until the time passes, until the sun alters the sugar, until the wind defines an unique structure and the humidity make it resistant.
