	As a matter of interest, ran some experiments on two small secondaries
yesterday.  They're identical except for one thing.  One is coated with
shellac, and the other with urethane varnish.  The shellacked (sp?) one
exhibits the static effect, the urethaned one doesn't!  By the way, it
was a rainy day.  Can't say what any of that means, if anything at all.
