I joined the Reaction Research Society when I was a teenager. It’s a rocket club, still going strong: rrs.org. We went out to the Mojave desert to launch homemade rockets. Some went up to a mile high, some exploded on the launch pad. They used a mixture of powdered zinc and sulfur, which burns very fast.
But at home I made some of this homemade rocket fuel. It’s made from saltpeter and sugar. My high school friend and I made some on his mom’s stove, but it got too hot and started on fire and filled the whole kitchen with smoke down to a few feet above the floor. 😯😯
