Nostril Air Redirection

The act of physically plugging a clear nostril on purpose when the other nostril is actually plugged in an attempt to force air to go through the plugged nostril to clear it up. Nasal decongestants are optional; in fact, this is typically done because nasal decongestants don't work for those times when one nostril is absolutely plugged to hell like a rush hour traffic jam and the other is like an abandoned highway. Despite common sense telling you that this is a genius idea and it should work, it typically doesn't. But that doesn't mean it never works, so be sure to try it next time you have a cold.
