Rocket
Definition:
(n.) A cruciferous plant (Eruca sativa) sometimes eaten in Europe as a salad.
(n.) Damewort.
(n.) Rocket larkspur. See below.
(n.) An artificial firework consisting of a cylindrical case of paper or metal filled with a composition of combustible ingredients, as niter, charcoal, and sulphur, and fastened to a guiding stick.
