Idea: self-foaming aircrete?

So there's a commercial on TV right now where a little girl is doing a science fair project where it foams up all over the place and makes a big mess.  Well that got me to thinking (and we all know where *that* can lead!)

The experiment is a classic science fair project called "Elephant's Toothpaste".  Basically mix soap, yeast, and hydrogen peroxide and it foams up all over the place.

Well that got me to wondering about making aircrete without all the fancy schmantsy foam wands and air compressors and whatnot.  Can't think of why this wouldn't work.  Soap is already used in aircrete, and yeast is just yeast.  No idea if peroxide would do anything to the cement tho.

Worst case, it should make a memorable-sacle mess.  If anybody decides to try it, let us know. ;)

I like the idea. Using peroxide with any reducing agent should work like iron filings.

I just had the same idea and found this Googling. Did you ever try it?
