The story for kids

This is E. coli, a bacterium that lives in our tummy, in our intestines, and it mostly helps us. It swims with its long little tail, which spins like a propeller. It eats sugar, and when it's full, it stretches and splits in two. When things are just right, that happens about every twenty minutes.
