Blowing smoke rings or the French inhale (blowing smoke out of your mouth and into your nostrils) are smoking tricks of yesteryear – how about vaping smoke through your ear? Pretty impressive, but according to a doctor on Quora, you can only perform this trick if you have "perforated eardrums."
"Smokers have some smoke entering their middle ear, but it (like the air inside it) is absorbed through the membranes lining that space. There would only be a way for the smoke to come out through one's ear canals if the tympanic membrane had a hole in it."
