Beakman explains that mold on bread is fungi and goes on to use models and animated clips to explain their structure and reproductive system. He also explains how they eat and get onto food to decompose it.
Professor Philip Brainard creates Flubber and tries to learn more about it. He performs quick tests on the physical properties of Flubber and finds that it is a highly viscous elastomer that can also phase shift between a liquid and a solid. Using observation skills, he also learns that Flubber is moldable, foldable, ductile, and elastic, among other properties.
Beakman creates a jello mold and explains the science behind how it solidifies. Since gelatin is made from animal bones, it contains collagen. When heated, it breaks apart, but when it cools it creates a matrix that traps the liquid which makes the jello consistency.
