[NewCandle] Measuring Half-Cell Charge

[Frederick Sparber]

Hi Keith, you wrote:

" I would suggest a stainless steel pipe rather than the copper float;
if you are using coarse carbon there is no need to pack it with
a ram, but you do need good electrical contact with the pipe
and copper oxide is poor in that regard. Some kind of
pressure on the carbon stack will greatly reduce the ohmic
resistance and improve the circuit also. It might be hard
to pack the copper float properly because of the shape."

I'm well stocked on vinergar and salt and a copper float, but no
stainless steel.

If only I could stuff a balloon into the float and inflate it.  :-)
