I made sonoluminescence in a similar flask at around 25.7 kHz. The water should be degassed SBSL to work. I suspect that if you added a little glycerin and took a long exposure, the set up you used would show signs of light.
@freemanx2x we drove the chamber at its first harmonic, but only had bubbles forming at the pressure antinode in the middle once. It was repeatable in that short timeframe, however, before our equipment deteriorated. The bubble formation was periodic: a small bubble would form near the centre and be drawn towards it. More bubbles would form and join with the first, until it grew too large to be held in the centre and floated to the top.
@shadym1lkman we were trying to create sonoluminescence. There's a lot of literature out there, and we followed a how-to guide, but deviated from many points due to limited resources (for example, our piezo drivers were from $5 speakers instead of the $150 ceramics the guide recommended).
Now try this with mercury under the stimuli if a torridial coil!

where the bubbles form? At the nodes of the standing wave?

did you create this experiment from scratch or is this a kit?
