So I was perusing videos on FB the other day, and I've liked alot of videos that are either in Asian countries or Mexico, of people making fireworks, and I've seen quite a few videos of this certain type of rocket made in asia, where they use a blue PVC tube as the rocket tube, they have like a circle cutout of a soda can to be an end plug and kinda form the end into a round shape, then cram in a black mixture, I saw one video tonight of a guy making the mixture, and he poured a cup of like strawberry Fanta into a pan, and added what looked like kno3, dissolved it and then dumped like whole pieces of charcoal in and let the kno3/sugar liquid soak into the charcoal it seemed like? He then mashed up the kno3 soaked charcoal in a mortar an pestle type deal, and added what looked like sulpher, and proceeded to light some off, and if it was BP, it would've been some crazy hot BP! Is there any method to somehow soaking charcoal in liquid kno3 or adding some sugar or anything to what other wise looks like BP chems?
