View full lesson: http://ed.ted.com/lessons/the-physics... In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around ... thirty-two times. How is this move — which is called a fouetté — even possible? Arleen Sugano unravels the physics of this famous ballet move. Lesson by Arlene Sugano, animation by Dancing Line Productions.
