Heat-changing dice are special dice made of an intelligent material that changes color when exposed to heat. Generally, such dice use heat-sensitive dyes or heat-sensitive polymers, which change their molecular structure when the temperature rises, resulting in a change in color. Among game players, such dice are widely used because they not only enhance the fun of the game, but also increase the difficulty and challenge of the game. In addition, in some scientific experiments or technological applications, dice that change color when exposed to heat can also be used to detect temperature changes and for certain special measurements and controls.
