Hot Cold Heat Sensitive Mug

Remember the Morning Mug, which had an outward appearance that changed, depending on the temperature of its contents? Another one like it is the Hot Cold Mug, although its design is much more plain and obvious.

Thermo-sensitive mugs are pretty cool because it’s like having two different mugs in one, but they also serve another purpose: they let the person know if their drink is hot or cold, and whether or not the body of mug is safe to touch. The Hot Cold Mug makes things obvious, because the mug just literally spells out whether the contents are “hot” or “cold.”
