Filling with vacum - creating foam

I think a very fun and utile would be teh ability to creat metalic foan at home.
We could have gas but we need to colapse bubles and take onli the likes that hold the metalic walls.

Ok.


Remenbering:

I did something fun.,
A 316l electrode inside a aluminum foil and left for some 30 days.
The electricity put in water continued until the 316l was completely foam like.

It keep in positive, because the  316l water-aluminum generated a bit of oxide, but curiously the water traped in the paper that hold positive electrode apart from the aluminum foils, kept working and working with some voltage.

It is a cell I can make that last too long.
Now about the Cell:

A cell inside a tube is heated. when he dry the voltage betwen aluminum/ 316 l is shorted.
REALLY shorted.

recipe: Alchemical Reference.
I did achieved two cristals one in front of ther - a yelow and a white.

Aluminum powder. - a safe mesh, we dont want explosions right?
316l Powder.

Put in a egg-vessel the 316l.
Folowing we put the aluminun powder.
Heat the vessel all day to 45 degrees.
Now:
Put a bit of water - Sufficient to keep powder up separated from 316l.
The oxide will build up in the time, we have a battery.

Fill with some water just to keep 316l powder away from aluminum powder.
Close the vessel with something while is hot.

Once the reaction and production of oxigen is over by the aluminum oxide, we
put this vessel (must be laboratorial) opened over a high fire.
The aluminum oxide would reduce?
For reduction of Aluminum there must be electrolisis right?
What about that?
What about fine  powder redution?


Understand. We have a battery!
The battery can make anomaly in relation to normal effects.
The battery could create a point of heat, where the droplet falls joining two poles, and creating a heat.
This heat could burn/spark consuming like plasma what is meat to be absorved by matter.
The secret of alchemy is a mistaken old knowledge.
