Performance artist sucks up particles into a brick

A performance artist has just finished a 100-day project to collect smog in Beijing with a special vacuum cleaner.

"I have commissioned a factory in Tangshan, Hebei province, where workers will squeeze the pollution particles stored in the vacuum cleaner into a brick in the next two days," said the founder of the project, who preferred to be identified as "Jianguo Xiongdi".

"Then it will be used for construction in the future, just as any other building material."
