A tumbler is a flat-floored beverage container usually made of plastic, glass or stainless steel.
Theories vary as to the etymology of the word tumbler. One such theory is that the glass originally had a pointed or convex base and could not be set down without spilling. Another is that they had weighted bottoms which caused them to right themselves if knocked over.[ citation needed ]
The modern tumbler comes in various sizes and shapes, designed to accommodate a wide range of beverages from water and juice to sophisticated cocktails. [1] Tumblers can also be adorned with decor, such as gemstones and rhinestones. [2]
The Janasena Party from India has been assigned a glass tumbler as a common election symbol being one of the twenty-nine political parties in India to have one. [5]
The tumbler is a measurement unit for cooking in the United Kingdom. 1 tumbler is 10 British imperial fluid ounces [6] [7] (1/2 British imperial pint; about 9·61 US customary fluid ounces or 284·13 millilitres).
The tumbler, the breakfast cup (8 British imperial fluid ounces), [8] [9] the cup (6 British imperial fluid ounces), [6] the teacup (5 British imperial fluid ounces), [8] the coffee cup (21/2 British imperial fluid ounces), [8] and the wine glass (2 British imperial fluid ounces) [6] [10] are the traditional British equivalents of the US customary cup and the metric cup, used in situations where a US cook would use the US customary cup and a cook using metric units the metric cup. The breakfast cup is the most similar in size to the US customary cup and the metric cup. Which of these six units is used depends on the quantity or volume of the ingredient: there is division of labour between these six units, like the tablespoon and the teaspoon. British cookery books and recipes, especially those from the days before the UK's partial metrication, commonly use two or more of the aforesaid units simultaneously: for example, the same recipe may call for a "tumblerful" of one ingredient and a "wineglassful" of another one; or a "breakfastcupful" or "cupful" of one ingredient, a "teacupful" of a second one, and a "coffeecupful" of a third one. Unlike the US customary cup and the metric cup, a tumbler, a breakfast cup, a cup, a teacup, a coffee cup, and a wine glass are not measuring cups: they are simply everyday drinking vessels commonly found in British households and typically having the respective aforementioned capacities; due to long‑term and widespread use, they have been transformed into measurement units for cooking. There is not a British imperial unit–based culinary measuring cup.
