Annie is driving a bus and sees a gap in the freeway ahead. She speeds up and successfully jumps across the gap. This clip illustrates a misconception about motion: the horizontal speed of an object does not influence how quickly it falls.
Aurora is swimming in the pool when the spaceship unexpectedly loses gravity. She is engulfed in the water, as it forms into a bubble and stays in place, and tries to escape. She finally escapes to safety when the gravity in the ship is turned back on.
Beakman explains flatulence and why our bodies build up gas that needs to be expelled. He explains how various foods affect the bacteria in the colon and that they release gas and cause it to accumulate. They also mention that the sound of flatulence comes from the anal sphincter.
Beakman explains different features of fingerprints, like whorls and arches. He then talks about how to find fingerprints and makes a DIY fingerprint kit. They explain how to use the kit to find fingerprints and match them to an individual.
Beakman explains how refrigerant inside of a refrigerator works and involves compression and heat absorption. He uses a demo of compressed refrigerant to show that, although it boils when not compressed, it's still cold. He follows up with an animated explaining how the inside of a fridge works.
Beakman shares some interesting facts about horses and their history. He also talked about how humans use horses. Then they show examples of different kinds of horses and their distinguishing features.

Beakman shares some interesting facts and features of whales. He talks about the blue whale and how it is the largest animal to ever live. He explains the differences between the two different types of whales based on their teeth.
Beakman defines machines and acts like Archimedes to explain why a screw is a machine. He illustrates how he used a screw mechanism to remove water from a container to reduce the amount of work required to complete the task. Beakman then explains more about mechanical advantage and simple machines like the inclined plane.
Beakman puts raisins in some soda and notes that the raisins rise and fall. He explains that this phenomena occurs because carbon dioxide bubbles from the carbonated beverage carry the raisins up to the surface of the liquid and that they fall back down once they reach the air.
