This could go in health and medicine, but really any health-related topic dealing with specific physiological phenomena is just as appropriate, in my opinion, in biology.
Hope I don't sound too weird here, but does anyone have any knowledge of the gas from carbonated beverages travelling through the Eustachian tubes to the ear, where something is affected, causing a funny sensation, and causing the head to shake, upon which the sensation subsides? Haha...yeah, that's totally weird. I'm not making it up though, honestly.
