Air is so ubiquitous and yet (if we haven't polluted it too much) so invisible. Have you ever considered air to even have weight? I guess it is true what they say: out of sight, out of mind. Not so for everyone, though. Thanks to scientists who have studied gasses and our atmosphere, we can tell you how heavy is air.
