Bransen111 Posted May 16, 2016 Posted May 16, 2016 Hey everyone, so I've mastered making rockets but now I'm trying to figure out something with some noise, part of the wow factor of fireworks for me is the noises and I still can figure out making things with noise. I lit a store bought fountain and it threw sparks in the air with different colors and also made a very loud crackling and popping noise and is like to learn how to start with something like that. I can't figure out how to post a video so I hope the description above will be good enough, thanks in advance for any advice!
