[NewCandle] Measuring Half-Cell Charge

[Frederick Sparber]

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.
