 All of this talk about crystal sets and razor blades reminded me
 of an incident about 20 years ago, when I was living in Boulder,
 Colorado.  

 I had just moved into a new apartment, and was using a razor blade
 (single edge "blue blade" to scrape some masking tape off a large
 window).  I was standing on a chair, and was thus somewhat insulated
 from the floor.  Now, Boulder normally has a thunderstorm in the
 afternoon on many days during the summer, and one came up while I
 was working on this window (on the inside).

 Suddenly a LARGE lightning bolt hit the top of the Flatirons, about
 3 miles away.  These are large monolithic slabs of sandstone that
 were tilted up at a sharp angle when the Rocky Mountains rose.  They
 are about 700' high (if I remember correctly).

 I received a h*ll of a jolt from that razor blade when the lighting
 struck.  Now this was a bit a a suprise, since although I'm familiar
 with induced EMF in antenna systems due to nearby strikes, I would have
 never thought that a razor blade had enough metallic area to collect
 enough EMF to be perceptable.  I believe it had something to do with
 the fact that at that moment the blade was in contact with a large
 insulator (the glass), and it rectified the current.  Any comments
 on this effect?
