Fun Gadgets - The On/Off Coffee Mug

Posted ideaonly on December 3rd, 2007 | Filed under - gadgets, Production Design

Ad your coffee to it and it changes colour from black to white and the message on the front changes from off to on.

In its dormant state, the mug offers a black “OFF” display, but once your hot coffee or tea hits the inside, it gradually transforms to read “ON”. A heat sensitive pigment changes the color of the mug from black to white.

While it may be designed for coffee, the $25 mug is Charles & Marie’s “Soupe du Jour” offer of the day. So if you want one in time for the holidays, you better grab yours now.
