Ron, Wouldn't it be lovely if peroxide were being formed on the (oxygen deficient) anode and then further spitting after a delay... but more likely, since the electrodes appear to be graphite, it is carbon related. Any idea what the composition of the (non electrode) gas, is?
Hard to see in detail... I'm sure that you aren't referring to halo of pulsing H2 bubbles that forms and spreads away at the top of the cathode but more likely to the smaller ring of bubbles which seems to appear a few cm away from the (oxygen deficient) anode ?
