- i would imagine that crystals added to a solution supercharged with
- gas would provide a great source of cavitation nuclei (minute cracks
- from which bubbles would grow due to vapor pressure differences
- overcoming the surface tension at the gas-liquid interface).

- you can test this 'physical' theory by tossing sand, sugar, or
- or whatever into some soda. i don't have any soda in the apartment
- and _won't_ waste a beer . . .
