Firecracker and firecracker arrangement

A firecracker comprising:

• a cylindrical outer sheath having two face sides, which is closed at both of the outer sheath's face sides with a layer of barrier material;
• a plurality of pyrotechnic effect elements arranged inside the outer sheath;
• a bursting charge arranged inside the outer sheath for bursting the outer sheath and for scattering the pyrotechnic effect elements;
• and
• a first ignition line which penetrates the barrier material at a first face side of the two face sides and which is guided up to the bursting charge;
• wherein the bursting charge is accommodated inside a completely closed, cylindrical jacket, with the cylindrical jacket being arranged in a manner coaxial to the outer sheath such that a longitudinal center axes of the outer sheath and of the cylindrical jacket coincide, with the first ignition line being guided through an opening in the cylindrical jacket to the bursting charge, and in that the pyrotechnic effect elements are inside the outer sheath and outside the cylindrical jacket between a cylindrical side wall of the cylindrical jacket and a cylindrical side wall of the outer sheath and are arranged to form a predefined geometric shape in at least one plane extending transverse to the longitudinal center axis of the outer sheath.
