|Portable oxygen bar.
Oxygen bars were a fad for a while, I think it's kind of over now, but you can still buy cans of concentrated oxygen (they say they are about 80%, compared to the 21% natural concentration in air) meant to be inhaled for non-medical reasons.
In a proper oxygen bar you sit around with a tube up your nose trying to look cool and pretend that you don't have a tube up your nose. In this portable version you're meant to inhale deeply while spaying the air (excuse me, the oxygen) towards your face.
Breathing air enriched in oxygen is a real treatment for conditions in which either disease (for example smoking-induced lung cancer) prevents the absorption of sufficient oxygen, or conditions (for example reduced peripheral blood flow) make it desirable to increase the amount of oxygen in the blood above its normal level.
Whether there is any benefit to breathing extra oxygen if you don't have one of these conditions is less clear.
