There was a large crowd huddled around the well where the ball of this Foucault Pendulum was swinging above a clock marking. As the seconds ticked by, as the ball moved from one zenith to the other in its swing, the tip under the ball approached closer and closer to a row of thin blocks waiting to be knocked over, each, I would assume, marking one minute in time. Eventually, one swing grazed the end block, sending it wobbling to the ooh's of the audience. It was the next swing however that succeeded in knocking over the block, drawing aah's from all around. As if the fall of the block marked the end of the show, the crowd dispersed, replaced by a new round of audience.
