I've never blown a CMOS chip either. I work on a bare chipboard bench (no
melamine or varnish etc) and am simply careful to touch the packaging and
board simultaneously while handling the chip. All this bathroom stuff seems
bizarre - do you get contact corrosion because of water trapped in the
sockets :-? BTW, conductive foam is much more usable than foil.
