The best of both worlds: the coffee stays hot, but as you tip it to drink it, it gets cool enough to do so without exposing your tongue and lips to molten heaven. That’s the idea behind the Brugo mug. And yes, if you’re weird and want it to be, you know, colorful, they sell happy shiny versions too. Freaks.
And while we were looking at that, we found energizing jelly beans (which when I was a kid meant they were hot cinnamon-flavored).
Mug and beans found via Strange New Products.
Update: Hey, they have caffeinated malt beverages too. Kind of pointless, though, isn’t it? Depressants + stimulants = right where you started, right? Whatever cranks your tractor, though.
