For safety and legal reasons, fireworks are often sorted into categories (like the European CE system: F1, F2, F3, F4):
F1 (Indoor/Very Low Hazard): Sparklers, party poppers, indoor fountains.
F2 (Garden/Low Hazard): Small cakes, rockets, and fountains for use in confined outdoor areas (e.g., small gardens).
F3 (Display/Medium Hazard): Larger rockets, cakes, and mines for use in large open spaces.
F4 (Professional/High Hazard): Large-calibre shells and powerful devices only for use by licensed pyrotechnicians.
A firework with a stabilizer stick that uses a lift charge to propel itself high into the sky before bursting into a single, large aerial effect.
A multi-shot firework that is essentially many tubes fused together in a single box. Once lit, it fires multiple shots in a pre-programmed sequence (straight up or fanned across the sky), creating a complete mini-display.
A long tube that fires a series of individual stars or small "shots" into the air at regular intervals. They create a lower-to-mid-level aerial effect.
A firework that remains on the ground and produces a steady, continuous shower of sparks, crackle, and colored flames. They do not launch projectiles and are generally low-noise.
A handheld wire dipped in a slow-burning pyrotechnic mixture that emits a constant stream of bright, glittering sparks.
A device that is pinned to a post and spins rapidly when lit, emitting a circular shower of sparks and often whistling or crackling.
