Here’s a neat innovation, a color changing coffee mug. And this is not just a concept, it is for real.
When you see the mug it looks like a conventional coffee mug with just the letters “OFF” imprinted. The real fun starts when you start pouring hot coffee or any other hot beverage, the mug literally changes its color completely from black to white and pops up the letters “ON”.
And ofcourse this is dishwasher safe but we do not have any information whether this is microwave safe. Overall, a really neat and very useful item.
Price ? Very affordable, $24.
