I’ve been trying to make different types of Stutata shells, but the issue with FWsim right now is that you cannot make a vertical-type multi-break shell. You can definitely try to get a similar result, but I do not know of proper solutions.
Nevertheless, you can attempt to make the single individual parts or a “fake” pre-assembled effect, but the perspective is key. This is what I could come up with.
The actual final controbomba effect is easy though, as it is a set of xsmall and spark-type stars with position and speed randomness. The two rings have a custom farfalle tail and the second one is rotated to 30 degrees to simulate the two rings used in the firework manufacture. (sadly no parallel rings, but works to a certain extent)
Some time ago I proposed this in a thread. Please visit it and you might find some additional information. https://fwsimcommunity.discoursehosting.net/t/is-it-possible-to-make-a-shell-of-shells-explode-vertically/
