How it's made

Source
two small air bubbles released under water, one after the other. Each rings as a damped sine at its Minnaert frequency, and the pitch climbs as the bubble rises towards the surface.
Body
a fundamental with a faint second partial (about 2x) that fades first, so the onset is round and the tail is pure. The second bubble is smaller and about a fourth to a fifth higher than the first.
Transient
a very soft band-passed noise tick (2-6 ms) for the wet "pop" of the surface film; no hard attack.
Envelope
a 4 ms fade-in avoids clicks, then an exponential decay of 50-160 ms per bubble; the pair overlaps slightly and the whole gesture ends by about 0.4 s.
Variation
`rng` detunes each bubble by a percent and shifts the second onset by a few milliseconds.
