Drinking cup that changes colour

A magic mug, also known as a heat changing mug, transforming mug, or disappearing mug is a mug that changes color when it is filled with a hot liquid. This effect is created by using thermochromic ink.

Magic mugs are often manufactured and sold as memorabilia. For example, a mug may reveal a picture of the town or monument where it was sold, for example the Haunted Mansion/Grim Grinning Ghost Disney cup.[1] They are sometimes given away to promote organizations. Customers can also have their own photographs printed on the mugs.[2]

In 2017, Panasonic introduced the concept of "smart magic mugs" when it showcased an in-car display table/screen that automatically rearranges the digitally displayed information around a mug when the latter is placed on it.[3]
