Click on the Fireworks icon in an empty scene. Once the network is built dive into the AutoDopNetwork and Double Click on the fireworks HDA. It will be greyed out when you are inside unless you enable editing of contents. But you can still see how it works. Basically it creates a group of dead particles and feeds that to a pop replicate. The pop replicate is what you would use in your situation to form the secondary spawn of smaller bubbles or mist by copying a small sphere onto those points.

POP Streams are just plain old point groups from SOPs. We actually call them “Group” by name on the various POP * DOP micro-solvers.
We had to find another name for “group” because DOPs have Groups already to create and specify Groups of Simulation DOP objects.
If you dive inside any of the POP * DOP micro-solvers you will see most likely a Geometry VOP DOP which is actually an equivalent Attribute VOP SOP working on the point geometry directly. In this world stream == group.
Knowing this is very important.
You can for example load up your incoming reference source geometry that you emit particles from with all kinds of point groups and point attributes and use them directly with POP * DOP micro-solvers.
You can partition your geometry via point groups in SOPs and then inherit these groups directly as streams in to the POP * DOP micro-solvers (which we now know are just point groups).
Hope this helps.

There's at least one school like the old school!
