Professor Whoopie Rides Again

Mechanisms are exciting for their own sake.  Folks like Arthur Ganson have shown us that machinations have their own mesmerizing magic built in.

But there's a special power in understanding what's going on in there.  This video is a perfect example of a clear, well paced mechanical explanation that starts at the beginning and moves in traceable, gradual steps towards an increasingly complex concept.  Its a perfect example of the kind of explanation Professor Whoopie, the man with all the answers drew on his 3D blackboard all those years ago.

Can iCarly or Hanah Montana explain how a rocket works?  Or why a sailboat goes forward?  Or how a lightbulb lights?  I didn't think so
