Really? Selling Air in a Can? Beleive it or not, Chen Guangbiao from China is selling air in a can for $.80 a pop. You can currently find these in major cities in China such as Shanghai. The air is compressed in the can so you can breath it in even after it is open. Is this what it takes for people to get serious about not polluting? We may think this is crazy, but than again, how many of us buy bottled water?
