Why do our ears pop on airplanes?

Have you ever been on an airplane and noticed that pressure in your ears? And then, as you’re taking off…they pop! Just like a balloon or a bubble or a freshly opened can of dough! Why does that happen? We asked infectious disease physician Dr. Frank Rhame to help us find the answer. Got a question that popped in your head? Send it to us at BrainsOn.org/contact, and we’ll fly in to help answer it for you.
