daily observation in physics - ultra-sonic clean (or bust!)
The tiny ultra-sonic fogger I recently placed in my indoor fountain effectively cleans the minuscule lime cover that stuck on the wide transparent blue glass bowl I've been using for indoor fountains over the past 20 years, resulting in two things:
First, the riffled transparent blue glass bowl is beautifully shiny again, adding a lot more flair to the LED lighting attached to the fogger.
Second, despite using distilled water for it, I now have to change the 2.5 liters in the bowl every other day until the lime is gone, or there is this ugly dust flake-like flotsam twirling in the bowl.

I should get a larger model to use on the bathtub...
