When my dad was a kid, he wanted to make "rocket candy" (solid rocket fuel made from sugar and saltpeter), so he melted sugar in one saucepan, saltpeter in another, and then tried pouring one into the other. However, it ignited on contact, and rapidly combusted, making a big noise and a charred mark on the ceiling.
I guess he should've only melted the sugar and not the saltpeter
Or maybe he was melting them together and heated the mixture up too much? I forgot the details
@wolf480pl I actually did this exact experiment when I was a kid. Made a smoke bomb to flush out a woodchuck from it's hole. It worked pretty well but man did that mixture burn hot. I had to stamp out some tall grasses that started catching fire around the area I ignited it.
@wolf480pl I "caramelized" them, poured it into a Tupperware and stuck matches in the top as a fuse lol
Probably a dry mix would have worked, but I had very little guidance in this endeavor besides "don't use any of my good pans"
@lurker but for a smoke bomb, dry mix would do, right?
