I have been experimenting with 300mg of a potassium perchlorate and magnesium based flash powder, but I'm a bit stumped on why it isn't, or rather is, making a bang. I've made it a few times, but it has not exploded, only making a bright flash of light. Though this one time it did explode with a loud and deep report. Question is why?
I didn't change the amount of mix or the percentages or the amount. The only thing that has changed is maybe the humidity of the air and time of day, nothing else. I've tried replicating the bang, but have not been successful as of now. Changing percentages or amount did not make a bang. Maybe someone here can shed a bit of light on this?
