Someone just recently posted a file that included a .gif and an address
telling where to buy the piezos...they had used the piezos attached to
either side of a flask, then fed with a variable oscillator feeding a
regular stereo amplifier...amazing that they get sufficient amplitude to
cause sonoluminscence....all can be done cheaply too....I don't have the
reference off hand and the archive is still offline so can't look it up,
but it was just within the past few days that it was posted here...if
you'll read the file, there is a contact you can click on for the
piezos...good luck and don't blow yourself up....
