My job here is done.
OK, it's not. This is the Pūrleve, described by the manufacturer as a hygienic door handle.
As someone who has mastered the art of opening and closing toilet doors without touching the doorknob, I've to admit that the idea of the Pūrleve is a good one: Every time someone uses it, a mechanism will cover the handle with an "antimicrobial-treaded sleeve." In other words: A doorknob condom.
As the company puts it:
Pūrleve reduces the amount of disease-causing germs and bacteria, helping in the global fight against germ cross-contamination.
Yes, yet another product that appeals to the global paranoia about infections and our hysteric need to sterilize the world. As far as I'm concerned, I just think that bathroom doorknobs are gross. [Purleve via Core77]
