Friday: a teacher

Last night Isaac made a circuit puzzle that he was so excited for me to do.  I finally did it this morning.  Then he was going to make one for Joshua.  As they were leaving the room I called out to Isaac to make sure it was pretty simple.

Ben went out a few minutes later and found Isaac trying to teach Joshua about a very simple circuit.

It's a bit hard to see, but Joshua just has to put in one piece in the correct orientation.  Isaac was so patient with Joshua, trying to tell him how to turn in so that the contacts lined up.  I think they kept at it for at least two minutes; I'm not sure who finally put it together in the end.
