    dont put your hand over the vibrating membrane of an ultrasonic humidifier while its on- ouch. The vibrating water above it HURTS when you touch it. (if you touch close enough). Its kinda cool though, how water vibrating can have an effect like that.

    Hmmm... I wonder why that is? It doesn't seem like water particles can have enough energy to harm our skin?

    It doesnt really "harm" you, maybe. It just hurts. It feels like getting zapped, kinda like when you hold one of those lightning globe things in a dry place and touch someone at the same time- but you're on the recieving end.
    Tiny things like h20 can hurt, such as when tiny stinging cells slash out their whips at you on jellyfish.

    Stick a fork in an electrical outlet if you want to feel what the nebulizer burn feels like. Notice in the manual DO NOT TOUCH THE NEBULIZER WHILE IN OPERATION. [img]http://www.**********.com/iB_html312/non-cgi/emoticons/wink.gif[/img]

    Yeah, that is good advice. don't think I'm saying to go try this. I'm saying Do Not try to put your hand over the thing.

    nep, there is no external voltage on the disc, it is simply the ultrasonic waves being transmitted through the water. The waves of course carry thier own form of kinetic energy which is converted to heat energy when stopped by your hand, fairly low power but does feel neet.

    Ah ok, Thanks Joe. I thought it felt similar to electrocution, probably due to the kinetic energy you mention. Thanks for pointing that out. [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img]

    I touched mine with my finger a while back. It felt like a burn. I think I even got a blister if i remember correctly. ...all I wanted to do is clean that gunk off. [img]http://www.**********.com/iB_html312/non-cgi/emoticons/tounge.gif[/img]
