After the Zinga dried there is infinite resistance between the two wires. placing an insulator on top of the wires and applying pressure the resistance can drop as low as 6M. The resistance varies with the pressure applied.
Piercing the Zinga with the meter probes I can get resistances from 40M (which is as high as the meter will read) down to the 100's of kilo ohms.
well, that's a pity!
The vinegar is a good idea, though the zinc will dull eventually.
