The cast members are bacteria. Their set is a large acrylic dish, four feet wide and two across. It is filled with a nutritious agar jelly that contains varying amounts of an antibiotic. The outermost sections are free of the drug—a safe zone in which microbes can easily grow. But as they move towards the dish’s centre, the concentration of antibiotic goes up in 10-fold increments, and conditions become increasingly deadly. To survive in these toxic zones, they need to evolve resistance.
