[NewCandle] Measuring Half-Cell Charge

[Frederick Sparber]

Sounds like a good idea to me, Keith.

I can change out the little-used activated carbon cartridge on my kitchen sink
high purity water tap and try it after I try it with distilled water.
A 1.0 meter dangle line should give a 2 second pendulum period for
the "bob" to settle down before switching on the voltage to the
deflection plates.
About 1.5 degree angle at one inch swing should be easy to see.

I can eke out 120 volts per meter with plates (supported aluminum foil) spaced
0.1 meter (~4.0 inches) using two 6 volt dry cell battery packs in series.
