Given that java tastes a great deal better when it's been brewed piping hot, the DD Smart Cup can help you decide when it's a safe time to finally take a sip. Most people have experienced a pretty painful burn from their fresh takeout coffees at some point because you don't receive a thermometer with your café order.
Tiago Pinto's packaging solution is a personal concept for Dunkin' Donuts paper coffee cups in which he suggests producing them with two layers of paint. Temperature-sensitive ink would turn the container bright orange when the beverage inside is over 70 degrees Fahrenheit. With this, a speech bubble would appear that reads "Take it easy! I am hot!" Once the liquid goes down into the 60-degree range, the thermochromic effect would dissolve, leaving the DD Smart Cup its familiar white.
