Okay .. I'm trying to set up an electrolysis of water demo ... and I
can't for the life of me figure out what is going on!

I have two test tubes ... two electrodes (cheesy ones), water with a bit
of NaCl to help conduct the electricity ...

The problem is that the negative electrode is going full bore ...
releasing gas like a good little demo ...

the other electrode is doing nada .. no gas ... no bubbles whatsoever!

Shouldn't I have gas on both?

Doesn't the evolution of gas on one imply that my circuit is complete and
e- are flowing and splitting water? What am I missing? This is driving
me nuts!
