Make Your Own Soda-Can-Sized Refrigerator

This DIY mini-fridge is impressive in its ingenuity, but confusing in its downright-uselessness. I mean, it fits a mere single can of soda/beer.

But hey, who am I to judge. It's got three coolers powered by a 55 watt, 5 volt power supply and it's all housed in PVC piping, making it look a lot like a pipe bomb. Hell, maybe that's the appeal of it. [Instructables via Engadget]
