You know the oxygen masks on airplanes? I don't think there's really any oxygen. I think they're just to muffle the screams. LOL

There's definitely oxygen received from o2 masks on the plane. They are there incase the cabin pressure drops. Without them everyone would pass out, because of under-oxygenated blood, and die..

But you are right! There isn't actually oxygen in those masks.
