Two men with bungee jump equipment on (belts and ropes) are standing on a platform high in the air.  One man is on the ledge getting ready to jump.  The second man stands slightly behind him, steadying him until he is ready to jump.  The man slides forward inch by inch until his toes are over the edge of the platform.  He raises his arms, nods his head, and pushes off the platform, the way a diver would jump off a diving board.  He falls, the rope attached still, a long down into a ravine, so far that is is hard to see him.  The rope snaps back just a little, then hangs still.  The rope has not bounced back up, and the man cannot be seen.
