Some explanation is needed for what it means to "complete the maze." 

From the web site referenced in the downloadable lesson was a link... but sorry, the link went dead. I guess I should have quoted more of what it said other than just this:

quote:

The object is to move the loop around the bends in the wire shape, from one end to the other, without letting the loop touch the wire. if the loop is very small, this can be very difficult to do!

The loop = that P shaped wire.

Nathanael, the author of this lesson, had come up with a sketch of a "wire maze." I'll include his sketch here.

I hope this helps.
