Cause everyone needs to know when their coffee mug is on or off, there is now a visual indicating On-Off Mug that reads "off" without liquid and "on" when filled with a warm bevy. A special heat-sensitive pigment will turn the mug from black to white as the temperature increases, so you not only get your morning cuppa joe, but you get a magic show as well. Each mug is dishwasher safe and costs $25. What do you think? Love or leave?

That is so chic! Everyone at work would love it haha!
1That is SO cool! I'd so get those!!!
2I think they're fun!
I'd like to see one that says Don't Talk to Me when it's full and Talk to Me when it's empty too!
3i really really really love this!
4Awesome!
This reminds me of a mug I used to have where the moon
would get darker and darker depending on the heat of the liquid.
5this is super cool!
6I love it. It reminds me of two mugs, one from Denny's that would go from a night scene with an owl to a morning scene with coffee in it. Also Kodakgallery.com has one that is blank, but when you fill it up, your picture is on it!
7I love it! so neat!
8i like it but not for 25 bucks!
9that's soo cool.
10a little expensive but... hey it changes clothes with heat.
haha very cool!
11definitely geeky chic!
12I saw these the other day, totally cool. I'd so use it.
13too bad it doesn't come in metallic pink or turquois, and said "b*tch" when empty, and a smiley face when full of hot java.
it's too cute though.
14Stupid. Leave it.
15OMG. I WANT.
16I love it! I want to get one for myself and a friend.
17This is so cool. I want one!
18That is awesome. I have a color-changing mug for cold drinks, too, but it's too cold in my house to ever start off at the right color!
19Love it
20It would be better if it said something else. On/Off doesn't really make sense, and my sense of humor is disappearing as I get older.
21that's so cool! i'd love to have that
22i love color changing things - i love those mugs!
23My boss would luv this!
24I think it is a cute gift for your coffee-addicted and techie co-worker... (hint hint)
25so cool!
26Love it for the office.
27I think the color changing on it is cool but it something else would better on it. and I certainly wouldnt pay 25 fo;r it
