I seem to remember a picture in S&T mag about this.... many moons ago. Not that it would look that black in a picture. Maybe it wasn't a picture, but just the same description of a sample on a table top. -----Original Message----- From: Andy Saulietis also mfg by Ball Aero. Looking at a sample on a table top, it looks like there's a black hole there. Andy Saulietis
