Thermochromism is 4u!
The deal with color-changing mugs is that, when hot liquid is added, a new picture magically (OK, magic is relative) appears. While it's more fun to pretend that they're the product of Hogwarts-style magic, heat-sensitive mugs work through something called thermochromism. Heat-sensitive mugs are made with special paint that takes advantage of thermochromism by swapping shades based on low and high temperatures. Think of these mugs as adult mood rings that use body heat to read your emotional state. It's the same concept, more or less.
Now, go forth and gift your buddy or bae the perfect color-changing mug based on his or her personality.
