That would be the Daily Mail using their precious Internet space to tell us about China's idea to sell bottled fresh air in order to "address its dangerous smog levels." In fact, such is the demand for that sweet, sweet O2 in China that one businessman already "sold 10 million cans in just 10 days" last year. As the depressingly popular Alex Jones remarked when spreading this story, "You really cannot make this stuff up." Well, yes, you can, because it's mostly crap.
The article makes it sound like China's president personally commissioned the bottled air to fight smog. In reality, he was just joking, because of course he was, and he never mentioned China's smog problem; he was talking about ways to promote the clean-aired Guizhou Province, the same way New York City once promoted its tap water with the exact same stunt. Guizhou tourism officials did take the joke seriously and announced plans to sell canned air ... as novelty souvenirs, not a solution to an environmental crisis.
As for the businessman who sold millions of cans of fresh air in 2013, yes, that's accurate -- if you replace "sold" with "produced," "millions" with "thousands," and "fresh air" with "the fetid air from his soda factory." Basically, it was the equivalent of Mars shipping off a bunch of empty M&M packets as a publicity stunt.
"All cans are just harmless old Chinese lead."
