Only in the last 200 years have humans learned how to make things cold. Johnson explains how ice entrepreneur Frederic Tudor made ice delivery the second biggest export business in the U.S. He also visits the place where Clarence Birdseye, the father of the frozen food industry, experienced his “eureka!” moment. He then travels to Dubai to see how mastery of cold has led to the possibility of penguins in the desert.
