Ear Popper relieves middle ear pressure discomfort
Aside from the tasteless food, bad movies, and whiny children, the worst thing about air travel is the uncomfortable sensation of middle ear pressure changes during take-off and landing. While homebrewed solutions like chewing gum sometimes do the trick, nothing works better than the Ear Popper (at least according to the NIH) in relieving your discomfort or in making you look like you're working your ear drum with your wife's back massager. This handy device blows pressurized air into your aural cavity and forces it up your Eustachian tube when you swallow, which experts claim to be quite effective. Fortunately for Wrigley's and Bubblicious, the Ear Popper is only available by prescription, so their monopoly on in-flight remedies is safe for now.
