There's nothing worse than burning your tongue on a cup of too-hot coffee...or having to down a lukewarm cup that you've been to busy to sip.

A new product solves that problem!

Coffee Joulies are little coffee-bean-shaped metal thingies (technical term) filled with 'an advanced phase change material that melts at 140°F.'

When you put them in hot coffee, that stuff inside the metal beans melts and absorbs the excess heat, bringing your coffee to an ideally sippable temp of 140. Then as the drink cools off, the heat transfers from the beans back to your drink...brilliant! According to the instructions, you do need to be able to put a lid on the cup for the joulies to work.

Only downside? The price. A bag of 5, in a little pouch to carry them around in, costs about $60.

Ehhh, that's a little pricey for me. Looks like I'll have to continue blowing on the cup before I take a sip.
