Canned Air Now for Sale in China
Guangbiao Chen, a Chinese entrepreneur, launched a product that might make some of us just scratch our heads: canned air.

According to Chen, selling the said product will help raise awareness about China’s pollution problems.
Chen said, “If we don’t start caring for the environment, then after 20 or 30 years our children and grandchildren might be wearing gas masks and carrying oxygen tanks.”
What more can I say? Canned air now for sale? I’m speechless.
