Yeast Starter - part 2

When I checked on the yeast starter this morning it had doubled in size, nearly filling up the bowl. I transferred it to a larger bowl and fed it again, according to the instructions. Now I'm worried that it will overflow the new bowl. I put it in the largest glass (non-reactive) container I own, but it's only about twice the volume of the first one. It will just have to do. The yeast should be all set to be made into bread by tonight, if I have time. I also did some Googling for directions on keeping the yeast alive indefinitely. You can keep it in the fridge and just take it out once a week for a feeding. It'll be my new pet! My smelly bowl of microbial goo pet. And you all will eat the bread I make and love it.
