During the cold winter, people always prefer holding one cup of hot coffee at hand. Under this circumstance, there is a design of creating an interlayer in the bottom of a jar, separating reactants and water by aluminum foil as well as controlling the heating process through the bottom button so as to keep the hot coffee for longer time. Amazingly, it only takes a few minutes to heat the coffee to a proper temperature. The outer side of the jar uses a special insulation mat in order to prevent hands getting burned.
