Just Wait for the Saturday Morning Cartoon (and matching Breakfast Cereal)

For some reason my children have this idea that yeast is a superhero. I believe this stems from several years ago, when they asked how bread is made. I've made sourdough, so I tried to explain that these invisible particles, called yeast, float through the air and land on the dough, eating the sugar. Their toddler-boy minds probably most enjoyed the description I gave them on how the little yeasties make the dough actually rise, but I'll leave that up to your imagination.

Anyhow, it's become quite a rock-paper-scissors-dynamite type game, where whomever claims to be the yeast ends up winning by default. For example:

Thing 1: "And then I'll be the giant who saves everybody."
Thing 2: "Then I'll be the Papa who saves everybody."
Thing 1: "Well, then I'll be the super-fast robot who wins."
Thing 2: "I am the super-fast robot whose batteries don't run out."
Thing 1: "Then I'll be the yeast."

At this point an awed silence comes over the both of them as they consider the wonder of this amazing creature.
