A Physics Lesson From the Master Himself: Gum Bands, Elastics or Rubber Bands

"The world is a dynamic, chaotic mess of jiggling things, if you look at it right."

In Boston, they call them elastics.  In Pittsburgh they call them gum bands.   But the rest of us call them rubber bands.  I'll bet you never considered them nearly as much as Richard Feynman did. He used some of this very knowledge to figure out why Christa McAuliffe died.  Yeah, he's that cool.
