A Firework Launcher is required to use a Small White Rocket. (see Notes section)
(Unlike several of the Lunar Festival fireworks, this item cannot be crafted by Engineers.)
requires that you launch eight Lunar Fireworks (color and size not specified) and two Cluster Fireworks (color and size not specified). Small White Rockets are a Lunar Firework, but they are not vended near the area of the quest, so are not a convenient item to use to complete the quest.
Unlike many fireworks in WoW, Lunar Festival Rockets (Large and Small, any color) require the presence of a Firework Launcher object on the ground in order to use the firework. These are widely available during the Lunar Festival only; near Lunar Festival revelers in cities and in Moonglade, and at other odd locations (there's some at the fishing dock in Orgrimmar). Firework Launchers are available year-round at the party at Saltheril's Haven in Eversong Woods. You can also spawn your own Firework Launcher for 30 minutes by using a , made by an engineer from schematics purchased from in Moonglade during the Lunar Festival. The schematics cost 5 . The Firework Launcher item does not bind; it has only one charge and is used, not equipped, so it is Consume on Use.
