Fujiko Nakaya is the daughter of a physicist who spent his career studying snow crystals, which may explain her own practice: she has spent over 50 years making sculptures out of fog. Nakaya’s first fog work was created for the 1970 Osaka World’s Fair. It used a system that generates pure water mist, an idea she’s been refining ever since in gardens, forests, and plazas around the world. For this show in Berlin, Nakaya’s installation is a sculpture garden that fills over time, at intervals, before dissolving into the sky. —Elena Clavarino
