Try one of these caps

Perhaps it will last a little longer :)

Are you running anything at all now for protection (I.E. a safety gap)?

Hey all, 
I have a bank of 12 beer bottle caps. The bottles are Corona brand and
method 
of construction is salt water and some vegetable oil inside the bottle
(of 
course) and aluminum foil  around bottle. Then electrical tape was
wrapped 
all around the foil exept bottom. 1/4 in. bolts are mounted in the
bottle 
caps and just slightly extended into the salt water. I was powering my
coil 
with a 9/25 nst and it worked ok (12 bottles may have been a little
much). 
But now I'm using a 15/30 nst. The max output was 24 in. streamers, but
now 
the bottles are failing on me and I'm currently down to 8 left. The
cause of 
failure was that the glass under the foil cracks and the salt water
seeps 
through shorting out the two plates. Can anybody shed some light on
this.

I also plan on getting at least one more 15/30 nst and wiring them in 
parallel. I currently have no protection filter for my nst. What is an
easy 
and cheap way of making one.

Thanks,
Lance
