Can a giant sculpture fit through a mail slot?
For its new London headquarters, the biomedical research charity Wellcome Trust commissioned a sculpture for the eight-story atrium— but the work had to fit through a standard-size door. A ground-level pool suggested the idea of capturing the dynamic shapes of falling liquids. The studio experimented 400 times with pouring molten metal into water to create unique forms, finally selecting a two-inch piece as a model to be replicated, ninety-eight feet high, using 142,000 glass spheres suspended on steel wires. The work’s title means "lead pouring" in German.
