Heartea is an interactive mug, which when touched, shows the liquid’s temperature. A small bulge emits blue, orange, or red light indicating cool (0°C–35°C), warm (35°C–75°C), or hot (75°C–90°C) drink. A heart-shaped, magnetic card on the bottom provides space for a custom message. The cup is designed by Sangmin Bae of ID+IM Design Laboratory for Nanum, a charity project donating all profits to educational scholarships of needy children.
