Put bacteria in a test tube with food and oxygen, and they will grow explosively, doubling in number every twenty minutes or so, until they form a solid, visible mass. But finally multiplication will cease as they become poisoned by their own waste products. In the centre of the mass will be a core of dead and dying bacteria, cut off from the food and oxygen of their environment by the solid barrier of their neighbours. The number of living bacteria will fall almost to zero, unless the waste products are washed away.
