Housing bubble

I was listening to a science show and the topic was bubbles, real bubbles, and how researchers have noticed for the first time that each time a bubble pops thousands of new very tiny bubbles are created, little bubble babies, and it of course makes one wonders if the same thing applies to economic bubbles. I suppose froth is the metaphor, no one can get traction in froth, people frothing at the mouth, froth at the factory pipe, all froth no beer.
