try using inst for faster electrolysis. I will be posting a forum using the electrolysis as an example if you are interested.
If you would like to see the whole physical effect (real life) change the Distilled Water to Salt Water. The electricity (spark) makes shows too well, and you don't usually see electricity in real life.
Putting in salt water makes it harder to see unless the view is in "Nothing Mode".
I know that the iron is not rusting or reducing, sorry.
