Get your valentine a special mug that will warm their heart…or at least the mug’s heart! As you can see on the right there, the heart on this mug changes color based on its temperature. So with a fresh cup of coffee, tea, or whatever else you like to drink at high temperatures from a mug, you get a fully red heart. As the mug cools and your stomach fills, the heart will return to its lowly black state.
This is a great little gift, and even something you can get for guys because it’s kind of sort of techy. It does have an 8-bit style to it at least. But be sure that nobody throws it in the microwave or dishwasher. Those will each ruin the color-changing-ness of the mug.
