Temperature-sensitive mugs are special drinkware that change color or display patterns based on the temperature of the liquid inside. When a hot beverage, like coffee or tea, is poured into the mug, it reacts to the heat, revealing vibrant designs or text. This feature adds a fun and interactive element to enjoying your drink. These mugs typically use thermochromic materials, which respond to temperature changes. When the mug cools down, the original color or design reappears. Temperature-sensitive mugs are popular gifts and can be found in various styles, often featuring themes related to pop culture, animals, or personalized messages.
