This is the Guinness Record holder for the world's smallest ad (yes, apparently there's a category for that), commissioned by Gillette and etched onto a beard hair (or is it a pube?) using an electron microscope and ionic blaster. The entire thing is only 100-microns across. How big are microns? Giant compared to yourcrons! Get it?! Me neither, but I'm still considering it a successful burn. *clips on sunglasses*
Hit the jump for a brief "making of" video.
Thanks to Martin, who sticks hair to the walls in the shower. That's nasty.
