In our daily life, we often find our windows fogging up on cold mornings in winter. This Heartwarming Window has previously been written by a special kind of paint so that no water drops can be congealed on the area it covers. On a warm day, this Heartwarming Window seems exactly the same with normal ones, however, when it gets cold, the fog on the window will form a warm tip reminding people to put on more clothes, which really brings warmth to people in cold winter.
