Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain fireworks and their kinds in general terms, relay safety rules, regulation and cultural history, describe how displays are organised by licensed professionals, and decline to provide manufacturing or modification instructions.

A low-explosive pyrotechnic device that produces light, colour, sound and smoke for entertainment, in forms such as rockets, shells, fountains, gerbs, wheels, sparklers, firecrackers such as cherry bombs and smoke devices, and traditional forms such as the Japanese hand-held tezutsu hanabi; fireworks are used in displays and celebrations worldwide, are made under strict manufacturing licences and are regulated for sale, storage, use and safety because of injury and fire risks.

What it is for: Entertainment through light, colour and sound.

It can be explain kinds and effects in general terms; relay safety and regulation; relay cultural history; route to licensed professionals.

Distinguishing features

What it looks like

Devices in paper or cardboard casings producing bursts of colour and sparks when lit.

How it is recognised

Pyrotechnic device for entertainment

Rockets, shells, fountains, gerbs, wheels, firecrackers, smoke devices

What the second pass must settle

  • Should consumer fireworks and display fireworks be separate entries?
  • How should national regulations be linked?
  • The registry entry has merged aliases naming specific devices and a brand-like term; should they be split off?
