The most common use of a firework is as part of a fireworks display (also called a fireworks show or pyrotechnics), a display of the effects produced by firework devices. Fireworks competitions are also regularly held at a number of places.
A gourd is a plant of the family Cucurbitaceae, particularly Cucurbita and Lagenaria or the fruit of the two genera of Bignoniaceae calabash tree, Crescentia and Amphitecna. The term refers to a number of species and subspecies, many with hard shells, and some without.
The gourd is larger than those typical of the maracas; the calabash is most common. The end is cut off but farther from the round body of the gourd, so the neck can be used as a handle. Strings of the same length are cut and tied to a center circle of string.
