Their name, as implied, simply refers to a classic doughnut or torus shape, and they exist purely to create a better, more leak-proof seal between two other components, with the aim usually being to prevent the unwanted escape of gases or liquids. In this sense, they're effectively a type of gasket - the main difference being that o-rings are more commonly used in very high-pressure environments, where a normal cork, paper or rubber gasket would likely be prone to failure.

We get it - you don't fly a plane, so what do you need one of these for. But though pilot's watches were originally indeed designed for those captaining aircraft, today the genre encompasses a whole slew of practical, rugged timepieces that can easily take many forms. From simple, time-only models recalling watches from the 1940s and 1950s to complicated chronograph, pilot's watches truly run the gamut.

Lawn ornaments are a type of yard art that may include designs depicting children at play, or various animals and nature. Nature lovers may enjoy yard art depicting birds in flight or perhaps deer in a natural habitat setting. These may be casual and made from a heavy plastic, or more elaborately constructed with more costly materials such as brass. And you can also place some Plastic Ducks as a decoration or even as Pet Toys for your lovely dog.

A mug is a type of cup typically used for drinking hot drinks, such as coffee, hot chocolate, or tea. Mugs usually have handles and hold a larger amount of fluid than other types of cup. Travel mugs (introduced in the 1980s) generally employ thermal insulation properties for transporting hot or cold liquids. Similar to a vacuum flask, a travel mug is usually well-insulated and completely enclosed to prevent spillage or leaking, but will generally have an opening in the cover through which the contents can be consumed during transportation without spillage.
