Where I would start is the humble message digest or hash.  You can use 
it for so many things, that if they walk out understanding this exists 
they'll be better for it.  You can also drop in there that the secret of 
Bitcoin is nothing more than elegant use of hashes, and they'll be all 
gooey and happy that they've got an insight.

that always does what he knows is wrong to do ;-)
