No doubt he meant "induction crushing".  Tim, if you are discharging your
caps into a few turns of heavy wire to crush a can, etc., then you need caps
with low internal resistance to transfer as much power as you can into the
coil and not within the cap.  Ideally, you should use pulse rated caps
designed for such severe service.

On the other hand, if you are discharging your caps through a spark gap in a
fluid (e.g. water), then you should use your 12 or 25 KV cap.  You will
produce huge pressure waves that will blow up cans, and can be used for
forming small sheets of metals into a mold, etc.

If you are discharging your caps into a thin wire to produce long, loud
discharges, then it will depend on the nature of the wire as to which caps
will work the best.
