Everyone's making this sound a lot harder than
it is! :o) See the size wire in a 2 amp glass
fuse? Get a strand of bare copper wire the
same size, pulled from a multistrand cable.

The fine wire is 2cm long and placed next to
the piezo, then use a couple of thick copper wires
(car jumper leads?) and a 12v battery or 10 amp
battery charger, etc. Making sure the fine wire
is close to the piezo and secure, touch the
big lead on the battery terminal. The little
2cm strand wire will vaporise very well!

For repeatability, keep cutting and using more
little wire pieces. This should be very easy
and safe, but I would WEAR GOGGLES.
