Inside Shanghai's cavernous Yuz Museum, there's a two-story metal box.
And inside that box: a fire hose dangling from a chain.
Every hour, the hose fills with water and dances about, spraying in a frenzy for just one minute.
"It's like a Chinese dragon," says Karen Cong, who's 25 and works in digital advertising.
Private museums like the Yuz are sprouting up along the riverfront in Shanghai, part of a government plan to build a Museum Mile on the waterfront and help turn China's financial hub into a cultural capital as well.
