What is a Thermos?

A Thermos is a vacuum flask, a type of insulated container that keeps its contents hot or cold for a long time. It is made of two glass flasks, with a vacuum between them. The vacuum prevents heat from escaping or entering the flask, so the contents stay at a relatively constant temperature.

Thermoses were invented in 1892 by Sir James Dewar, a Scottish chemist. He originally developed the Thermos to store liquid nitrogen, but it was soon adapted for use in other applications, such as keeping food and drinks hot or cold.

Thermoses are now used by people all over the world to keep their drinks warm on a cold day or cold on a hot day. They are also popular for camping, hiking, and other outdoor activities.
