	Well, I must admit, this is not a rigorous test of dielectric of 
vegetables, but I once took an old cord with the plug still attached off of
a defunct appliance.  I stripped down the bare end of the cord, put one
stripped wire into one end of a pickle and the other stripped wire into the
other end of the pickle and plugged the cord into the wall socket.  Mostly,
the pickle fizzed, but it did glow a little.  The effect is much more
dramatic with the lights out.  If I had it to do over, I would put the
pickle on an insolating material.  I've never tried radio frequencies,
sugar beets or potatoes but my guess is that they wouldn't work as well.
