New inventions constantly revolutionized the industry and Jewett chimed in with one of his own: the self-heating can.



The can had a central chamber containing a substance that would release heat when put in contact with water. Water could be dropped into this chamber and the resulting heat would cook the surrounding vegetables.



Jewett claimed it was "just the thing for light housekeeping, picnics, camping, yachting, sportsmen, etc."
