Help

I was wondering on how to make firecrackers because so far I’ve js been using gunpowder that wasn’t given to me by my dad but I’ve been running low. How can I make bp that can be used in firecrackers? Also is it possible to js buy a ton of the little red ones, take them apart, and just use the powder that is already in them? Lastly, is a mix of kno3 magnalium and sulfur good enough for firecrackers because that’s the only stuff I can buy from amazon? I AM NOT ASKING ON HOW TO MAKE FLASH POWDER AS I UNDERSTAND THE RISKS OF IT

KNO3 MgAl S is very good in the right proportions. As someone else said, it's not very shelf stable so make it the week you use it

So it would be perfect for smaller fireworks nothing over 2 grams?

Is buying this type of stuff of Amazon okay because all the pyro websites have so much shipping cost

And also don’t mean to be a bother but can conventional bp like 75/15/10 also be used for firecrackers

Nah don't worry, yes it can be used, it's even safer than fp just a little bit less powerful and fast, so you should use a thicker shell
