I will post sources to make fireworks. Some of the best Youtube channels I find in fireworks are:

Ned Gorski
Viking Pyrotechnics
Night Hawk In Light
Pyrotechnic Tutorials
Vh718
and of course, DisplayFireworks1

Watching firework factory videos is also what triggered my knowledge. My favorite factory videos are of Italy, Malta, and Australia(Howard And Son's Pyrotechnics).
