| Fortissimo User | When I worked with a certain aero-space manufacturer they used to test jet engine components. They had pits in solid, concrete floors and the pits were lined with 8" of lead. They'd attach a piece (say, a turbine disc?) onto a mandrel, lower it into the pit and spin it at ever-increasing speed until it blew up (sometimes around 30 - 50,000 rpm). Solid lead at room temperature would splash like it was liquid (which it probably was during that instant of time). Those pimples are really neat... wonder if they're possibly volcanic rather than "meteor splash"? |

| Oh, I don't know much about such things but I never thought they were part of any meteoric activity. I was referring to the, well, craters.Those "pimples" definitely look like the leftovers of Martian volcanoes. They look snow-capped, don't they? Probably not but it looks that way. Anyway, thanks, Jerry... very cool. ML |

| That was fascinating, Jerry! However, I could have done without a synthesized verion of "Marriage of Figaro". How many dozens of recordings with real orchestras have to exist out there? Whatever, it was still nice of you to post that. I'll show it to my kids. Have a good one! ML |
