Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group, since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water.
Polyurethane refers to a class of polymers composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many different applications. These include rigid and flexible foams, and coatings, adhesives, electrical potting compounds, and fibers such as spandex and polyurethane laminate (PUL). Foams are the largest application accounting for 67% of all polyurethane produced in 2016.
The Duck family is a fictional family of cartoon ducks related to Disney character Donald Duck.

It creates a unique, deep barbecue flavor and the roast is usually coated with a flavorful sauce before roasting. Siu mei is very popular in Hong Kong and Macau, and overseas Chinatowns especially with Cantonese emigrants. In Hong Kong, the average person eats siu mei once every four days, with char siu being the most popular, followed by siu yuk in second, and roast goose being third. Some siu mei such as white cut chicken and soy sauce chicken are not roasted at all but they are still considered siu mei nonetheless. siu mei is also known colloquially as siu laap, as the latter term encompasses siu mei and laap mei, a type of preserved meat. They are usually prepared in the same kitchen during autumn and winter season in what are often known as siu laap establishments or Chinese BBQ shops. Siu laap is also often sold alongside lou mei, such as orange cuttlefish and Pig's ear.

A fire extinguisher is a handheld active fire protection device usually filled with a dry or wet chemical used to extinguish or control small fires, often in emergencies. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user, or otherwise requires the equipment, personnel, resources or expertise of a fire brigade. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent that can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist but are less common.

Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter derived from sources such as the offshore breakdown of algal blooms. These compounds can act as surfactants or foaming agents. As the seawater is churned by breaking waves in the surf zone adjacent to the shore, the surfactants under these turbulent conditions trap air, forming persistent bubbles that stick to each other through surface tension.
