What can't R2-D2 do? Well, now it seems he can also humidify the air with the cool new R2-D2 USB Humidifier. If your office here on Earth is as dry as Tatooine, then Artoo can help add some much needed moisture to the air this winter. Just lift R2's dome top, fill his body with water, shut the dome and plug him into your computer's USB port. Cool, soothing mist instantly blows up and out from his head using Piezoelectric technology, something stolen from the Empire by Rebel spies I think.
