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.
Wax Gourd, also called White Gourd, is a fast-growing, long-season, warm-climate vegetable. The plant produces fruits on vines, like the pumpkin on ground, which can grow up to 50 pounds. Fruits can be stored in a cool place for months and used later in the winter season. Thus this gourd is called Tong Qwa, meaning Winter Melon in Chinese. The unopened fruits can be kept fresh for a long time, but the flesh shall be used in cooking within a few days once the fruit is cut into pieces. NOTE: Wax Gourd needs insects/honey bees to carry out the pollinating process for setting fruits.
