Automatic Hot/Cold Mug Takes Your Coffee’s Temperature

by Paul Strauss

A little while back, I told you guys about a nifty coffee mug that could automatically change states from “on” to “off” when a hot beverage hit its surface. While that mug turned out to be insanely popular, many of you pointed out the fact that a simple change in the design to read “hot / cold” would make infinitely more sense. Well ask, and ye shall receive.

The gang over at Charles & Marie listened to your feedback, and have worked with Dutch designer Damien O’Sullivan to produce a new version of the minimal black-and-white mug that says “cold” when it’s cold, and “hot” when it’s hot. It’s amazing how one small text change can really make such a difference. Heck, just the utility of knowing when that coffee that’s been sitting in there all day long is cold as ice should be enough to merit the $25 price tag.

Charles & Marie is now offering the Hot/Cold mug on a pre-order basis now, so if you want one, you’d better head on over and place your order. They should start shipping in about three weeks.
