Hello Reddit! I am a certified pyrotechnician. You all showed the interest so AMA!!
I would like to say a special thanks to /u/StickleyMan for making the suggestion.
Now, I will start off by saying that I have been around fireworks all my life. I do know other stuff but in light of the 4th of July or any other holiday in the world that fireworks are used to celebrate, I will be here to answer questions as well as any other questions you can throw at me. I only have one request and that is....
Please don't ask how to make bombs or what not. I WILL NOT ANSWER. The internet is a big world. Some stuff out there is very dangerous to handle.
I have provided proof to the mods. I will try to answer as many questions as possible. I have literally set the rest of my day to be dedicated to your questions.
Well what are we waiting for, Ask away!
