"Hey wow!  I'm Elron Duck now!"

"But that's not how it comes out of the factory.  That's how it comes out of the dispenser.  Out of the factory it just looks like a roll of butchers paper.  Only when it's stretched does it create that texture."

"There's no design flaw with the directionality.  If there's no rewind, it doesn't necessarily mean that the spindle can only rotate in one direction.  Since the arm can be pivoted from one reel to the other, I would assume that the spindle would reverse direction on that action.  So no matter which orientation of the drive spindle, it will always be pulling the tape and never pushing."
