Tate Modern’s "Sunflower Seed" Exhibit by Ai Weiwei Closed as Health Risk


LONDON (AP).- British art museum Tate Modern says an exhibit involving 100 million porcelain sunflower seeds has been closed to visitors because it is a potential health hazard. Chinese artist Ai Weiwei filled a giant hall at the London museum with a carpet of the imitation seeds, made by thousands of workers over a two-year period. Visitors were invited to walk across the surface when the show opened earlier this week. But the gallery said Friday that the “enthusiastic interaction of visitors” was causing a dust cloud that could be harmful if inhaled over a long period. It said visitors would no longer be allowed to walk across the seeds, though they can be viewed from a walkway above the hall.
