The third basic rocket propellant is the venerable black powder which is available from sporting gun stores. However, the powder used in the traditional muzzle loading arms is more powerful than that used in the rockets. To make a rocket powder from the hunting powder approximately 40 grams of fuel (charcoal or sugar) are added to every 100 grams of the hunting black powder. The charcoal may be made from barbecue brickettes broken down and screened for size.
