Make bubbles rise at their own speed, wobble and merge into bigger ones

Bubbles that all rise at the same speed with the same wiggle look like a pattern, not like water. Big and small bubbles behave differently, and when two touch they should become one without the screen suddenly gaining or losing bubble material. Here is how size drives the motion and the merge.

Why this works

Real bubbles differ by size in everything at once: bigger ones rise faster but only a little, swing wider and slower, and joining keeps the amount of air, not the width. Letting size drive every property makes the whole group feel consistent.

When not to use it

Skip it for a large crowd of bubbles, such as a foam or a fizzy drink, because checking every pair gets slow. Use a cheaper look there: no merging, just a few sizes drawn in layers.
