Neil deGrasse Tyson on Mary Poppins, Kites and Physics

How high could a kite fly? Could it get into the stratosphere? What are the physics of kite flying? How do updraft, buoyancy, string weight, kite weight, and wind speed interact with each other? The answers are supercalifragilisticexpialidocious, as Neil also weighs in on the kite-flying scene in "Mary Poppins" -- and unlike some other Disney movies when it comes to scientific accuracy, this one passes with flying colors! This Cosmic Query also features Eugene Mirman starring as the "funny person." (For the explanation of that one, you'll have to watch.)
