Have you ever experienced your ears popping before? Why does this happen? Well, you ear has a small pocket of air in it that, usually, has the same pressure as the outside air. However, when you are on the takeoff or decent of a plane ride the atmospheric pressure of the air around you is constantly changing at a fairly fast rate. Inside your ear there is a small tube which is made for equalizing the pressure of the air in your ear and the air outside your ear. This opens when you swallow and often when it is opened you hear a pop; and that is the pop you hear. The bigger the difference in pressure the bigger the pop. So next time this happens to you, don't be scared...its completely normal!
