Here is a quick update about the aluminum in KOH solution:
YouTube - aluminum in KOH solution video2
As you can see, after 5 days there is still a gas production going on. The aluminum piece has became smaller. The reaction has also became less intense, that might indicate that the KOH is also consumed in this reaction. You can see all that black gunk on the bottom of the jar, that is aluminum oxide.
Thanks,
