(Visual) Tests  of (one type of) the Dallas_Gold_Bug Electrodes.

Tap water VS Distilled  water

I employ a plastic box generally  used for perserving  spaghetti , a small 12V/4AH Bat and a Clamp Amp Meter.  No gas measurements are (still) done.   :((

With tap water : The meter is showing about 2  amps.

With dislilled water: nothing is perceptible (gas production-wise)
and the meter is showing few mili amps.

This is an expected behavior... .but, perhaps not a definitive
comportment, (with another device) ?
