The rocket is a pyrotechnic product containing one blow and is mounted on a wooden mallet – so called ballast. The stabilizer must be flat and not damaged. Wooden gavel is freely inserted into the fixed tube and subsequently the fuse is ignited. After the igniting of the fuse, it is necessary to step back into a safe distance. Rocket will fly up and create a colored lighting effect in the sky. Particular care should be given to the stabilizer, which after the explosion of the rocket falls back to earth.
