I think you may be underestimating your kid here. Try to walk him trough the steps and see if he can't grasp at least some of the magic.

  As good as we can, consider it done. But that's still not the same as being able to trace the wiring or to follow the mechanical linkages. What I found really interesting is that they have no problem understanding vacuum tubes but fail at understanding transistors which are essentially the same thing only going from a literally transparent glass tube with inner bits that you can see to a little black piece of plastic with three metal legs sticking out. There's a lesson in there somewhere.
