Apparently, pure oxygen is a real pick-me-up. So if you find yourself getting really sluggish at work and don't want to rely on coffee to give you a burst of energy, this portable oxygen bar wants to be your alternative to caffeine.

Sure, it might be kind of weird for your coworkers to see you sucking from a tank of oxygen at your desk, if it helps you feel better at work it might be worth the embarrassment. Whether or not it's worth the $660 pricetag, well, that's another issue entirely. Maybe sticking to Starbucks isn't that bad an idea after all.
