Anyone fancy buying a sculpture made from 80,000kg of human poo? Mike Bouchet’s pungent piece, The Zurich Load, is making visitors to Manifesta 11 in Zurich feel rather queasy. (Anyone who excreted faeces in the city on 24 March contributed to the site-specific work, which the artist created in the Werdhölzli wastewater treatment plant.) But if no one stumps up for the excremental creation, it faces annihilation. A spokeswoman for Manifesta tells us that if “no potential buyer emerges, The Zurich Load will be burned following the usual process in waste management”. Just goes to show that shit happens.
