Buoyancy - USS Holland submarine simulator

[WernherVonTrapp]

I actually stood on top on the original sub when I was a teenager. It used to be on campus at J.F.K. High School in Paterson, NJ. Had my picture taken on it, though I don't know what happened to it over the years. Now, I think it's housed in some old museum in the downtown section. It's a pretty small sub. Smaller than a standard transit bus but, about the same girth, if my memory serves me right.
