Abstract
An infant drinking cup is described. The infant drinking cup is a first color when at room temperature. When the cup is filled with a cold beverage, the portion of the cup below the fill line changes to a second color. When handled by an infant, those areas below the fill line in contact with the infant's warm hands change color back to the first color. The process is fully reversible, such that the infant drinking cup can change from the cold color to the warm color, and vice versa, repeatedly.
