A fireworks rocket is, like each rocket, an aircraft, which moves itself by recoil. At the peak point of the flight path usually different effects (stars, Crackling of star, etc.) are ejected.


A fireworks rocket consists usually of the following elements:

  • a propellant charge
  • an effect charge/a pay load
  • a Leitstab

The fuel in the propellant charge is mostly black powders, which transmit-producing materials, as rough charcoal or aluminum and iron splinters for a beautiful spark tail are mixed. The propellant charges are optimized on the optical effect and less on the achievement. This differentiates the propellant charges from fireworks rockets in principle of the model rocket propellant charges.

The effect set in the point consists of dragierten flares, which can be present in addition, in cylinder form. For the achievement of a flame coloration and as oxidizing agents different alkali metal nitrate is used at the same time, as barium nitrate for green, sodium salts for yellow and Strontiumnitrat for the red coloration. As fuel serve usually sulfur, charcoal and/or different resins. Silver sparks are produced with additives of metal chips, like aluminum or magnesium. For distribution some more roughened, loose black powder is given to the effect charge at the peak point of the rocket flight course last to the nose cone.

So that the rocket straight ascends into the night sky, a Leitstab is laterally glued to last. This is responsible to the rocket in air for the clean flight path and prevents a "estimating". There were also occasional fireworks rockets, which are stabilized similarly as correct rockets by tail fins. Although these rockets are smaller than such with and also without special Startvorrichtung be started can, these designs for fireworks rockets not to intersperse to have been able itself, since these fireworks rockets stressed a larger place in the stands because of their higher volume. Also there were occasionally problems with flight stability.

Colors are produced by adding following elements and connections:

  • Red: Strontium salts (dark red), calcium (orange), lithium (carmine)
  • Yellow: Sodium salts
  • Green: Barium salts (yellow-green), copper (emerald green), tellurium (grass green), thallium (point green), zinc (pale green)
  • Blue: Cuprous salts (azure), arsenic, lead, selenium (light blue)
  • Violet: Cesium, potassium
  • Magenta: Rubidium
  • White, silver: Magnesium, aluminum, titanium, zirconium
  • Gold: Iron, coal


Fireworks rockets of the class BAM-PII may be sold in Germany only to fully competent persons (starting from 18 years). There is nevertheless each year a high number of partially heavy injuries, which are caused by an inappropriate handling. In the large fireworks fireworks rockets are replaced due to the increased safety margins ever more by fireworks bombs, which are fired from mortars.
