[NewCandle] Measuring Half-Cell Charge

[Keith Nagel]

Sorry if I'm overengineering this thing, but we'd be talking about
several thousand times the force if you use the carbon so it's
worth some consideration.

Here's a thought. What if you just filled an insulating container
with the carbon and electrolyte. Now you have an aqueous phase,
which is the "outside" of the container, and the carbon phase,
which is the "inside" oppositely charged?

That's pretty easy to do, and I think it accomplishes the
same thing, yes? No packing required, and no ohmic connection
needed...

Keith,

I just wanted to see if a water filled copper float would feel a force
in a`120 volt/meter E field due to Contact Electrification and
electron exchange between the water and copper.

And added experiment would use salt water as you suggested, but
add a bit of distiied white vinegar to remove oxides etc., from the copper.
