On/Off Coffee Mug

by Paul Strauss

This simple, clever mug automatically indicates its current state of mind when you pour a hot beverage into it.

On Off Mug

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.

    Nice idea, but am I missing something. Should it not have displayed HOT and Cold…

  2. Sicko says:

    It’s neither “just plain fun” or good design. Sad design, boring and $25 bucks!? I’ll pass.

    Somebody must have peed in Sicko’s Wheaties today.

    “indicates its current state of mind”

  6. is this for cofee only? how about other drink?

  7. David Dunn says:

    I quite like the idea and agree with Coqui that the cup should display HOT and COLD instead.

    I also think that the price is a bit steep, if it was lower I may be tempted to get one of these.

  8. Jasmin says:

    40 $ Shipping for a 25 $ mug … weird.

  11. technabob says:

  12. Hanadi Al Sayed says:

    Dear Sir,

    How can I order (on/off mug)?


  13. Pete says:

    Hm.. daylight robbery. 15 Euro Cup ships for 15 Euro. And this the cheapest way to ship .. hee heee. Shipping from some distance galaxy?


  14. gMoney says:

    Cool concept, but the pricing is a bit much for a coffee mug. I think i’ll use my hands to see if the mug is warm or not.

  15. John says:

    Is it true that Charles&Marie (the makers of this mug) use child labor to make their products?

  16. says:

  17. Neil says:

    Looks cool, but I’ll be fked if I’m paying 25 bucks for a mug.

  18. says:

    This mug “looks really fun” on the ad but I got one from my hubby for Christmas and it is not all it’s cracked up to be! First, the cup NEVER turned all white except for the letters when it was hot. The worst part is that someone, maybe me, put it in the dishwasher and yes (it can happen) the black PLASTIC film, melted leaving it useless as far as I am concerned.
    That was $20 plus shipping down the drain and I am rather ticked at the moment! This idea is all good on paper (not even on the cup) but not worth the money AT ALL! I guess if I did it, and I don’t know because I have been sick these past few days, and don’t remember, I figured maybe it was ok to put it in the top shelf of the dishwasher since the microwave didn’t hurt it. Oh well, lesson learned. Just use my normal stuff and stop trying to amuse myself with wastful (not needful) things

      Hmmm. I’ve had mine for almost 5 years now with no problem at all – but I’ve never microwaved or dishwashed it – only put hot coffee or tea in it, and handwashed it.
