There are three ways of heat transmission: radiation, convection and transmission. The silver cup in the mug can reflect the radiant water, and the vacuum of the cup and the cup can block the heat transfer, while the bottle which is not easy to transfer heat can prevent the hot convection. Thermos flask, also applied the principle of magnetized water, is in the bottle bottom and cap plus magnets, so that water is magnetized.
