Ear Beer [Video]
This girl can drink an entire beer through her ear!!
If this is legit she's sucking the beer through her Eustachian tube, that's the tube that connects your ear to your throat. But, who really knows how to build it's strength? Are there some Eustachian exercises you can do?
However, it's also possible that the beer is being spilled through the bottom of the cup. You never really get a good look at it. In addition, the straw is of course white so you can't see if the beer is really coming up through it.
