Saltwater cap option?

Until I get the caps for my MMC ordered
from the Geek Group, I want to give salt water
a try (not having to make SW caps again will
help me to justify having spent the bux on the
MMC :).

I was watching the kids drinking their Kool-Aid
brand 'Burst' drinks, which come in soft plastic
containers.  I checked the bottom and it says its
low density polyethylene.  Looks to be virgin
material, its milky translucent.

Most of it is 0.025" thick, the bottom corners
are closer to 0.009".  Each one gives me a bit over
20 square inches of plate area (at 0.025").

I think I could hot glue or epoxy up the original opening 
in the top (a 1/4" hole) and cut holes in the bottom
to add water and terminals.  Basicly just use them
upside down.

That should give me somewhere around 400pF per
bottle, with a conservative voltage rating of 3kv, or
maybe 6kv if I want to push it.  I think.  If I put 6 in
series I get about a 18-36kv rating and about 60pF.

Does this sound useful at all, or should I go for a
party cup cap instead?

Thanks
