Lagenaria siceraria (synonym Lagenaria vulgaris Ser.), bottle gourd, opo squash or long melon is a vine grown for its fruit, which can either be harvested young and used as a vegetable, or harvested mature, dried, and used as a bottle, utensil, or pipe. For this reason, the calabash is widely known as the bottle gourd. The fresh fruit has a light green smooth skin and a white flesh. Rounder varieties are called calabash gourds. They come in a variety of shapes, they can be huge and rounded, or small and bottle shaped, or slim and more than a meter long.
The calabash was one of the first cultivated plants in the world, grown not primarily for food, but for use as a water container. The bottle gourd may have been carried from Africa to Asia, Europe and the Americas in the course of human migration. It shares its common name with that of the calabash tree (Crescentia cujete).
A craft is a pastime or a profession that requires some particular kind of skilled work. In a historical sense, particularly as pertinent to the Middle Ages and earlier, the term is usually applied to people occupied in small-scale production of goods. The traditional terms craftsman and craftswoman are nowadays often replaced by artisan and rarely by craftsperson (craftspeople).
