This one won’t burn your tonue.
It’s rather unpleasant when we judge the temperature of hot tea or coffee wrong, and burn our tongue as a result. The smart mug, equipped with a built-in thermometer, is designed to prevent such accidents. On the side of the cup, six tiny lights signal whether the drink is still too hot, ideal for consumption or too cold.
The mug is thermo electronically operated, which means that no batteries are needed: the energy required for operation is gained from temperature changes.
