Yes.
WTF is the point of washing your hands when you have to touch a door handle to get out of the bathroom? You know freaking well that half the dudes who passed through ahead of you didn't wash their hands before leaving...

That's why you get the paper towel and use it to turn the door handle. Also, don't eat the pretzels.

Thanks for that.
My paranoia hadn't reached bar food yet.

I do that but it's annoying that I have to. I also don't like touching the paper towel dispenser handle. Life would be far less complicated if they just had good hand-dryers and automatic doors.

Well, when you stick your hand into what is, effectively, a 100mi/hr slipstream that is larger than your hand the wind is exerting something like 30-40 lbs/ft^2 which is a pretty good push that you feel quite well. But it is a different story when air is exiting an orifice. Because of boundary layer flow and something called the 'no slip condition,' when air exits an orifice it is not like a wall of air at constant velocity, the velocity of the front is a gradient curve looking something suspiciously like a normal distribution curve, where the center peak is max velocity. As soon as that air exits into the quiescent room air it decelerates massively. My understanding is that it is a thin beam, if you will, of air also. So when you combine the the facts that the peak velocity is not at all the average velocity of the beam, that it decelerates on exiting the device, that the flow is much disrupted and likely is entraining room air and going turbulent, and that this 'beam' of air is acting on a much smaller surface area of your hand than when you stick your arm out of the window, I'm not sure the physical effect would really be all that great. 400mph does seem excessive, but if its measured right at the orifice and with something very tiny like a little pitot tube (which actually measures pressure and they back out velocity from that), then 400mph is not too unreasonable. ~ H

Is this the same Dyson who works for Cyberdyne Systems? If so, I can't in good conscience buy his products.

-The jet air dryer, which blows air out of the unit at claimed speeds of 400 mph, was capable of blowing micro-organisms from the hands and the unit and potentially contaminating other washroom users and the washroom environment up to 2 metres (7 ft) away.

Ok I didn't read it all.

But from what I read, I'm better off drying my hands on my shirt or pants than using a hot air dryer?

I've tried that joke twice already with no success.

I have to say that I don't get the paper towel on the bathroom door handle thing. I only began noticing it about 5-6 years ago. Throughout the day, you touch far more worse things than a bathroom doorknob. If you think about it, the TP itself and dispenser was touched by some dude wiping his ass. Do you get a napkin to get the TP? I know, you wash your hands after all that stuff and don't want to comprise their "integrity" by touching anything after you wash them but seriously, you ain't gonna catch the ghey by touching a doorknob that some other dude left some pen0r or rectum DNA on. Also, if there is someone in your office/school that ain't washing after wiping, he is also touching all sorts of other doors and things that you are coming in contact with anyway.

Well, if no one got it the first two times, maybe visual aids aren't such a bad thing...
