Tumbler (glass)

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.

Originally, the term tumbler referred to a type of drinking glass with a pointed or rounded base, which prevented it from being put down until it was empty, encouraging the drinker to finish their beverage in one go. Over time, the design evolved into the flat-bottomed glassware that is known today, which can comfortably sit on tables and counters without tipping over. The modern tumbler comes in various sizes and shapes, designed to accommodate a wide range of beverages from water and juice to sophisticated cocktails. Tumblers can also be adorned with decor, such as gemstones and rhinestones.
