I finished putting the capacitor together the other night.  It is only about
5nF, when it should be 10nF.  But wow did it work.  From a coil that used to
give me 2" sparks now gives at least 2" streamers and 6"+ arcs.  That's with
only 4 static gaps, and half the required capacitance.  I will eventually
build an MMC, i'm just gonna mess around with this setup for now and think
about a bigger coil.  I'm gonna build another cap this weekend to put in
series with the other one, i've just gotten approval from my physics teacher
to bring it in to school (after i work safety considerations into the
presentation of course)

I will post pictures (hopefully video too) on my dad's FTP site when i get
around to it. (i'll post the address)
