Funkology: Battery Mug

Now there's a new way to know how much energy you have for your work if you rely on coffee most of the time. This battery mug indicates the strength of the content, by all means the amount and temperature of your coffee.  When your coffee is getting cold or running out, the battery indication at the side will decrease.  On the other hand, if the coffee is hot and fresh, filling up the whole mug, the battery will showed as full.

Battery mug available for $28 from here.
