    My range hood has touch button controls. Just the slightest touch of a finger changes functions. I never gave any thought to how this works. This morning, I had just finished wiping my hands with a paper towel and had it still wrapped on my hand. I touched the button to turn the exhaust fan on with the finger covered by the paper towel. ..... Nothing..... I pressed a little harder..... still nothing. I took the paper towel off and brushed the button ever so lightly. The fan came on. How does that work? Obviously, it's not pressure that turns it on. But what?

    My iPad doesn't work through a paper towel either...no matter how hard I press.

    Maybe we have already been implanted with the chip and paper towels and having damp fingers interfere with the chip connecting to our tech gadgets!:eek:

    It must be brand dependent. The appliances in our house are touch controls.
    • I leave finger prints on them, when I use them.
    • My wife fusses at me for leaving fingerprints
    • My wife wipes the fingerprints off with a bounty towel and the stuff turns on and off and changes settings, etc.
    • Which is apparently all my fault.
    I can fold a single sheet of bounty and simulate 2 sheets and both my Kindle and Smartphone (LG) work. I can fold the sheet over again, simulating 4 sheets and the Kindle no longer works, but Smartphone does. Another fold to simulate 8 sheets does not work on the Smartphone.

    I did not attempt any of this on the appliances, lest my wife see me and think I have committed to a new precedent.

    I just tried again with a single layer paper towel on my finger and couldn't get it to type on my iPad.

    Okay, here is an explanation.

    BTW, I went back and tried the 8 fold and used more pressure and the result was it worked. I needed to further compress the paper towels for the finger to come close enough.

    Stylus... which actually better explains the process...

    What is body capacitance... Nice read on Wiki.

    I'm still not using a paper towel to operate the microwave, stove, etc. I'm going to use them the way God intended. :p

    That's some explanation @Harry Havens. Thanks for finding the answer for those of who really wanted to know that. And even those of us who didn't.

    Most of the time I don't care how something works...as long as it does work. :)

    And so @Harry Havens is all that explanation basically saying something like our fingers are sending little "shock waves to our touch pads and microwave touch controls and making them work? And the paper towels and in my case sticky or damp fingers blocked those little shock waves? :)

    I really try to be that way, but often I get consumed by curiosity.

    Yes. I would also say that if you compressed the paper towels, while rubbing your sock feet on the carpet... it might work as well. :D

    Very good, @Harry Havens. I looked for an answer to this one, so that I could pretend to have known it all along, but didn't find anything that made sense to me.
