Not Telling
So the most powerful flash powder I've noticed on the internet is the Potassium Perchlorate and Dark Aluminium Powder, I'm making an order from a polish website to make some firecrackers but Potassium Perchlorate is hard to buy without license and that, so I've figured out that u can replace the Potassium Perchlorate with Potassium Nitrate, is that right?
give me an answear and an explaining to it 
This is the 2 Powders that I'm planning to mix
