When making rocket fuel we used two different methods; gunpowder and rocket candy. We wanted to see which would work better with the rockets. When making the gunpowder we used 1 gram Carbon, 1 gram Sulfur, and 1 gram Potassium Nitrate ground down to a fine powder. The result was that the flame was small but easy to light. We tried again with the the powder not being as finely ground down and the powder was not as easily lite. Our conclusion was that the finer the powder the easier it is to light.
