Tired of burning your tongue on coffee,
only to have it get cold a few minutes later?
Well, Joulies claim to solve the problem. Inside each stainless bean is a special phase change material (what ever that is), that melts at 140 degrees F. Put them in your coffee and they absorb heat when it's too hot and releases heat as your coffee cools off.
Kinda pricey at $100, but wouldn't it be great to never burn your tongue again, on hot coffee.
Has anyone tried the coffee Joulies? I'd love to know what you think!
