Does anyone know how to make rocket fuel for model rockets.?
I’d never heard of the “sugar rocket” jtobako mentions, it sounds neat. Way back I used to hear about zinc-sulfur fuel. Here is some data http://en.wikipedia.org/wiki/Solid-fuel_rocket Zinc-Sulfur (ZS)Propellants Composed of powdered zinc metal and powdered sulfur (oxidizer), ZS is another pressed propellant that does not find any practical application outside of specialized amateur rocketry circles due to its poor performance (as most ZS burns outside the combustion chamber) and incredibly fast linear burn rates on the order of 2 m/s. ZS is most often made novelty propellant as the rocket accelerates extremely quickly leaving a spectacular large orange fireball behind it. “Candy” Propellants Candy propellants are generally an oxidizer (typically potassium nitrate) and a sugar fuel (typically dextrose, sorbitol, or sucrose) that are cast into shape by gently melting the propellant constituents together and pouring or packing the amorphous colloid into a mold. Candy propellants generate
