Oxygen for Sale
I think this is kind of a cool idea.
Japanese convenience store operator Seven-Eleven Japan has breathed fresh air into its product lineup by announcing it will add cans of oxygen to its shelves.I wouldn't mind getting a blast of O2 every now and then when I'm feeling worn out.
The firm said it would make an entry into the rapidly expanding oxygen market and begin selling cans of oxygen on May 24.
A drop in the amount of oxygen in the body can make people start to yawn and sigh. Normal air contains only about 21 percent oxygen, but the oxygen concentration in the cans is 95 percent, and breathing it in can reportedly bring on a feeling of invigoration.
Each can contains enough oxygen for 35 two-second inhalations, meaning each can lasts for roughly a week if it is used five or six times a day. At first the canned oxygen will be sold in Tokyo, Kanagawa and Chiba prefectures, then at all 11,000 of Seven-Eleven Japan's nationwide stores from June 14.
