Tropical Vacation: Newsletter Challenge (09/11/07)

Posted September 09, 2007 5:01 PM
Pathfinder Tags: challenge questions

The question as it appears in the 09/11 edition of Specs & Techs from GlobalSpec:

You and the family take a trip to the tropics for vacation – a nice change of pace from home in the desert. Arriving at the hotel, the windows in your room are flung open, but the kids won't take the hint and walk down to the beach. When they aren't jumping on the bed, they're dragging their socks across the damp carpet. Fortunately, their attempts to zap each other are futile. Giving up, the youngest finally asks, "Why don't you get a static shock when the air is humid?"

(Update: Sept 18, 8:42 AM) And the Answer is...

In a humid climate, a thin layer of water adheres to solid surfaces – even carpet. Unlike the water vapor in the air, however, this surface water contains minerals such as salts that provide grounding. Although the answer to this challenge question involves humidity, it's not because "humid air conducts electricity". While it's true that humid air contains water, the water in the air doesn't contain minerals. Therefore, humid air is not a good conductor. With the mineral-laden water layer on the carpet, however, even the kids socks don't have a chance to build up enough charge.

If you knew what I'd been thinking of saying about a possible trip to America, you'd have cut my tongue out and fed it to Del. . Having double checked, Chucks behaviour now seems clearer. Now that I am completely OT, I shall reveal the controversy over my silk PJ's and await some flannel.

Ah! Now I see what you meant. Revenge being a dish best eaten cold, I'm lying low and lulling him into a false sense of security. Mind you, I haven't seen him around for a bit.

"25 years + 2 days old!" ? Yeah, and I'm really Leonardo De'caprio

I was referring to the emoticon, not my own gorgeous, youthful self. I'd rather have Matt Damon....

PMSL about the "autograph pad" - reminds of a Dilbert series.

Yes Matt Damon does better films, though I don't fancy him.

This all great but for me it creates an important an interesting consideration. I snore. Not only is it a problem for my wife but it causes a sore throat and apparently brain damage (dont hold me to that). When I go to bed at night I occasionally experience static discharge when removing my clothes. I have always felt that my snoring and subsequent issues were worse during dry weather. Thanks to this challenge and the information provided I now have a natural costless snore indicator. So from now on. When ever I experience static discharge before bed. I make sure I tell the wife she should sleep in the other room if she wants a good night sleep. Thanks CR4.

You tell your wife that and you are the one likely to be sleeping in the other room!

Nothing static about this thread! Geography, sports, climate, social customs, celebrities, etc. What's next? Maybe the next off-topic topic will be something shocking!

The topic is about static electricity, so we are creating lots of static.

The tension is unbearable. We'll all get discharged for this.
