hydrogen peroxide plus aluminium equals ... what? Answered

I know that hydrogen peroxide and alcohol equals well"whoomph", but what happens if I mix hydrogen peroxide and aluminium?

Almost certainly nothing. Aluminum oxide forms very quickly on contact with oxygen -- but  unlike iron oxide, it remains attached to the aluminum and forms a barrier layer that stops the reaction. (Which is why aluminum is so corrosion-resistant.)

I don't think hydrogen peroxide can cut through that. Feel free to try it, though.

Nothing.  I doubt the Aluminum would even do much to increase the decomp. rate of the H2O2 more than a little.

Probably nothing much. Why don't you try it?
The most I'd expect is that the peroxide would decompose.

hmm... then do you know of anything I can use with H2O2 to make an explosive?

Peroxide has a tendency to decompose, for explosives you need it upwards of 30% - have you got that? If you have I can do some Googing, or you could. There's nothing here that I know of.

You would need to vacuum-distill it, and be very careful. I don't think this is a good idea as apart from being dangerous it's probably illegal.

I've seen it before, notice how it says "I am pretty sure the top one will be the Hydrogen Peroxide" - meaning it wasn't actually done it's just theory.
