This may sound very dum.

You need to be grounded to play the theremin ya?So if you wear rubber shoes shouldnt it not work?
And if you were in the sky would it work? or in a rubber room?

'cus typos! ( and bad grammer)

No, you do not need to be in electrical contact with the floor. The mass of your body is sufficient to act as an earth (U.S. ground) for the capacitor plates of your hands.

I have never played in the sky but I bet it would work. (I assume you mena in an airplane or somethng.)

Rubber shoes are no problem. I often wear my Dr. Martens and my playing is no more atrocious than usual.

Rubber rooms would probably be OK too, although I don't speak from experience.

Gordon?

D) Rubber rooms aren't OK, they are [i]great[/i]. But enough of my private life.

Z) Whoa, dude. It's not just you - there's no weird website conspiracy to deceive the Zakiman going on. Try it for yourself - find a non-conductor (http://www.filmhai.de/kino/kinoplakat/bilder_0011/sister_act_himmlische_karriere/gallery1/sister_act_001.jpg) to stand on and see if your theremin works.

The Principle of the Theremin bit
http://home.att.net/~theremin1/

It says ground blame art for my theory and not having a theremin to test it. Wait its not his fault i dont have one....

No, it's a reasonable question. I wondered myself a while ago.

Here's why. From Wikipedia: here (http://en.wikipedia.org/wiki/Ground_%28electricity%29#Circuit_ground_versus_earth).

[i]Circuit ground versus earth

In an electrical circuit operating at signal voltages (usually less than 50 V or so), a common return path that is the zero voltage reference level for the equipment or system. Voltage is a differential quantity, which appears between two points having some electrical potentials. In order to deal only with a voltage (an electrical potential) of a single point, the second point has to be connected to a reference point (ground) having usually zero voltage. This signal ground may or may not actually be connected to a power ground. A system where the system ground is not actually connected to earth is often referred to as a floating ground.[/i]

Oh, and I'd say click on the non-conductor link anyway, but it's a really lame joke, so don't bother.
