Many objects end up being used for something totally different than their original purpose. For example, the thermos was invented by a Scottish scientist named James Dewar, who wanted to keep some chemicals at a stable temperature.
He came up with a system where he placed a small bottle inside a larger one, and sucked out the air between the two bottles. This principle was used to create the modern thermos, which helps us keep our food and drinks at just right temperature.
