Discolor Stopper

Usually we will open the plug and then hand touch to perceive the temperature of the water in a thermos bottle. Thus, if it is hot, we must bear the risk of scalding hot. "Discolor Stopper" is a good solution to this problem. At the bottom of the plug equipped with a temperature sensor that can sense the water, when the water temperature is high, it is red. Then with the passage of time and the temperature dropped, it will gradually turn green, when it becomes completely green, it means the temperature is low, we need to replace the hot water.
