Personal Oxygen Bar
People get high on the strangest things these days, like oxygen. You may never have thought of oxygen as something people would use recreationally, but many high end spas and resorts charge around $1 per minute to breathe air with a higher concentration of oxygen. Another thing you might not know, too high a concentration can actually be harmful to breathe. These machines capture ambient air, filters it, and pumps it out with 43% more oxygen, which is the right amount to achieve the desired effects.
