Yep, points go to zanne68! They built this big tower out in the middle of nowhere, on the bank of the New River, to make lead shot. They'd drop molten lead from the top through a grating or sieve (to control shot size). It would form perfect spheres on the way down, land in a basin of water, and cool. *G* And there are only 3 in the USA. And it was in the early 1800's - the time of "Master and Commander", toosiemuppet! I saw it as I was driving through Southern Virginia and went "wtf?" It was just out there, off the highway, in a little tiny park. Cool. *G*

(Watching "House"... man, MUST he destroy the one friendship he has? God, I'm loving seeing both Wilson and House in this episode. Can I just say... what beautiful eyes they both have. *sigh*)
