Chemistry / Re: Methanol attacks aluminum oxide?

Thanks.  I don't recall what I was thinking when I posted my reply above about hydrogen generation with NaOH and aluminum; it has nothing to do with the original post and I apologize for going off topic.

As far as methanol removing the aluminum oxide film on aluminum, I agree with the fellow who wrote that it would likely be a slow reaction.  There is likely a catalyst which would help speed the reaction rate, but I cannot think what an appropriate agent would be for that. I have not used my chemistry degree in decades and my mind is rusty.

Anyone else have an idea for a catalyst?

Adding aluminum foil, sodium hydroxide (red devil lye) and water together creates a vigorous reaction and generates hydrogen gas, which is extremely flammable (remember the Hindenburg!).

You can add those constituents to a glass bottle (only use a little of each, about an inch at the bottom of the bottle) and use the gas to inflate balloons.
But remember, those things are flammable. You can put a match or an ember on the end of a long pole, such as those used to trim small branches from trees, and ignite such balloons. Even at that distance you will feel the heat from the exploding balloon.
I would only ignite one balloon at a time however. They really do make a large fireball in the night sky.
