Uh Oh!  Blown cap?  In a jam?  You can assemble .01uF
(12 pack) of beer bottle caps in a couple of hours and
be sparking again in time for your demo.  Just an
idea.

I like Gary's sucker gap too.  Lately, however, I've
been studying his vortex gap (sort of a reverse sucker
gap).  I just might have to try one of those, as I
have a big 120V centrifugal blower sitting idle in my
junk collection.
