Abstract

The present invention relates to a pyrotechnic system, system-compatible pyrotechnic objects, and a firing method tailored to the system. The system comprises a starting device having multiple receptacles, having a connection channel between each of the receptacles. The receptacles are filled with the pyrotechnic objects, the first receptacle is provided with an additional ignition device, and the pyrotechnic object located therein is ignited. An igniter externally positioned on the pyrotechnic object conducts the ignition energy into the interior and simultaneously via the connection channel into the neighboring receptacle. A pyrotechnic object located therein is ignited. The igniter externally positioned on the pyrotechnic object partially causes a time delay. The delay time may be set by twisting the pyrotechnic object in relation to the connection channel. The choreography of fireworks may be designed through the combination of a starting device with selected pyrotechnic objects in connection with the setting of the delay time.
