Disposable camera hack?

Hi, im building a capacitor bank for my coilgun, and I have 17 disposable camera capacitors in them.
(wired in parallel (or whatever one means + is atached to +, and - is atached to -))
But for some reason wenever I start chrging it, after a little wile, it makes a huge spark across one
of the capacitors. That probobly means its arcing right? but its only 300 volts
(there wired in parelell so only the amperage goes up, not the volts).


I then tryed to charge the caps to a point before they arced, wich took about 1 min (the battery is full)
and my ammo only shot 3 inches! 17 capacitors, charging for 1 min, and it slid across the floor
3 inches! I have no idea what im doing wrong. Im using wire from a microwave motor
(wich is realy small) for the coil, and its 5 layers thick, wrapped around a hollowed out pen.


So, to sum it all up, here are the main problems:
1) the caps arc when charging
2) the ammo only goes 3 @#%!ing INCHES!!!!!! arg!



Ps, i heard someware, that if you have enought amps, it will arc even with lower voltages.
Maby thats whats happening?




PLEASE HELP!!!!!! :(

All those sharp points of solder will cause the arc to form much earlier than if they were round points.  Put some insulation between the poles and that will help.
