Oil Change Picnic

We had an 8am appointment to get the oil changed in the van so we took our breakfast and a picnic blanket.

The boys watched the auto maintenance show and learned all about differentials.  I asked Elliot to point to the differential - I'm no expert, but I think he got it.

Interspersed between maintenance topics there were clips from the Big Bang Theory.  Those held the boys' attention as well.
