[NewCandle] Rolled Al hydrolysis

[Nick Reiter]

Hi Keith,

Bubblin!

Well, if it goes like the ones Sam and I have played
with, you should get some occcasional spurts of very
high bubbling amidst the level that you plateau at,
but then in probably 48 to 72 more hours it will begin
to diminish, then at about another 48 hours beyond
that, the Al will turn a gunmetal grey, and the water
will be visibly murky, and the bubbling will slowly
stop.

Now Sam claims that if you take the roll out, let it
drip dry, then bake it in an oven at 300F for a couple
of hours, once back in the water, it will kick in
again with about the same cycle.  MAybe baking cracks
open hydroxide layers or something.

Overall, its kinda novel, but without the "amalgam"
such as KOH or NaOH, its self limiting.
