On/Off Coffee Mug

This clever mug automatically displays “OFF” when it is empty and ‘ON” when it is filled with coffee or tea. It is covered with a heat sensitive pigment which allows it to change from black to white or vice versa depending on whether it is filled or not. Charles & Marie are now selling the mug for $25.

    on and off? why cant they just say empty or full? or hot or cold, or why not a smiley face for full - a sad face for empty. on and off makes no sense O_o

    I agree with Daniel. I think they could have done something much cooler with the design.

    …..aaand I’ve found my father a Christmas gift.

    Agree that on/off isn’t the greatest design, but he’ll still get a kick out of it!

    maybe the on/off stands for the caffeine. around my house, no one talks to anyone til weve had coffee because we are still half-asleep still. caffeine = “on” switch, im guessing.
