The team fills a pool with Custard to test whether someone can walk across without sinking as they would if they walked across water.

Beakman shows how to make glue from skim milk. He explains the steps and then says the glue is from casein.

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 explains that construction equipment is "strong" because of hydraulics. He demonstrates that when you try to compress a liquid, it has a limit. Pascal's principle says that the pressure is the same everywhere in the liquid so if you open the end of the syringe, then the liquid is forced out. Using this, they show how Liza can push down on one hydraulic shaft and this will cause the rat to be lifted. Basically, she does more work with less energy.
