Morgan talks to some health experts about the obesity epidemic in America and how fast food restaurants are a contributor to it. Lisa Young, a professor at New York University, illustrates how fast food companies have changed their portion sizes over time to make excessive amounts of food the norm.
Many of the local restaurants in the Pawnee Restaurant Association have increased the size of their sodas, and the city is concerned. Leslie argues that a 512 ounce child size soda may be taking it too far.
The CyberSquad creates a boat that is one-tenth the size of the giant's boat so that it can successfully navigate the waters to the portal. The group's first attempt at building the boat fails, as each part came from a different size scale model. The gang uses blades of grass as rulers and finds boat parts with the correct dimensions to create a properly-sized boat.
The CyberSquad needs to fix the train in order to get up the mountain. They manage to get it moving by putting in a missing gear; however, it travels too slowly. They note that gears of different sizes turn at different speeds and that a gear with a high number of teeth will make the train move fast when paired with a gear with few teeth. They swap out a couple of gears and get the train moving at a fast rate.
