Most people my age like a book; you can take it to work and read at lunch, in the bathroom, etc - however, the CD has some videos as well and I found them to be fascinating - at least on the version I have, there is a video of how aluminum tanks are extruded, very interesting for this non-mechanical guy -
are you doing the internship or the other option that I have never used and can't remember it's name?
if nothing else, you will know more about dive theory, tables, physics, etc than you thought possible - a couple years ago we had a DM class of 7 that calculated what it would take to lift a Ford Explorer off the bottom of the local quarry - and the maps they turned in were extraordinary - and how they did it was quite creative as well
