Acoustic magnetic generator.

It does. 
I always am amazed how much the glass can bend before it breaks.  I could not squeeze the glass so much in a vise statically.  It would break much earlier than the dynamic deformation shown on that video.

As glass is a liquid,i would think that some how the structure of the liquid is being changed by the acoustics-making it more pliable.Maybe John Hutchinson was really onto something?.

I too,have not seen glass flex this much without breaking.I wonder if the same could be applied to that liquid we can use as fuel!water!. Can acoustic resonance break the bonds of water?

@ tinman,

It can break, when placed in a crystal bowl and resonated at 42712.2 hz. Thats what John Keely observed. True or false, I dont know.

Would a setup like this work?
These are 16 ceramic magnets 8 on each side of the piezo element.

Pickup coils on each side moveable to find the acoustic nodes.

If the material of these magnets is susceptible to acoustic stimulation...then maybe it will work a little.

Pickup coils on each side moveable to find the acoustic nodes.

The disadvantages of this arrangement are:
- open magnetic flux path (high reluctance)
- short acoustic path (short separation between acoustic nodes)
- open ends radiate acoustic energy to air (acoustic energy loss)
- segmented magnets will cause acoustic reflections inside the stack, which will confuse measurements
- segmented magnets might clap if the stack is not clamped, which will confuse measurements further
- no core for guiding the magnetic flux (magnets have almost the same permeability as air) thus flux can loop back in unexpected places, not necessarily under the pickup windings!


P.S.
Don't you have a large ferrite C-core or a toroidal core that you can cut with a Dremel tool + diamond wheel ?
It's easy to damage this type of piezos by soldering.  Clip-on contacts might be safer...

Ok,  thanks, i have a ferrite C-core, but its not really large.  I do have some yoke halfs too, but those are not really large either.
By "a toroidal core that you can cut with a Dremel tool + diamond wheel ?" you mean cut it in half, or only one cut where the piezo would tightly fit in?

What about this setup (the rod is graphite which is conductive but not magnetic, so it would need to be a similar ferrite rod):
