The next morning, the group isn’t allowed to eat because they’re going to be doing parabolas in a plane (flying up and then down to experience zero gravity). It’s known as the Vomit Comet because people often throw up during the exercise. Liam finds the idea thrilling, but everyone else seems terrified. Everyone’s strapped in, and the plane climbs fast. Next, everyone except Monsieur Martinet unstraps their seatbelts and floats through the plane as it careens toward Earth. They do this several times, and eventually Monsieur Martinet throws up. Florida catches the vomit in her sick bag and finds it quite amusing. Liam handles the experience well. Once again, someone votes for Liam that day, but it isn’t Florida.
Florida researches gravity and astronauts online, and then starts her own version of gossip that Liam deems “astrogossip.” She finds a thrill in learning about astronauts, their relationships, and their children.
Liam finally gets a chance to prove his worth when the group is tasked with riding the Vortex, a gravity machine that spins them up to a force of 15g. While all the other fathers struggle to convince their sons to participate, Liam convinces Florida by explaining how great it will be to be the first ones and watch everyone else be scared. Liam finds the experience almost surreal, as though time is standing still and each thought lasts forever. He also feels flattened. When it’s over, Florida is impressed with herself, and Liam finds that he doesn’t mind it. He convinces Samson Two to go next and agrees to ride with him. The same follows for Max and then Hasan, who each want to ride with Liam as well. While on the ride, Hasan confesses that his family experienced war and that soldiers nearly kidnapped him. His father had to pay them off, and that’s why his father cares so much about money. Liam gets all four children’s votes that day, bringing him into a tie with Mr. Xanadu.
The final task is to use a flight simulator to drive a rocket back into the atmosphere from space. Max goes first and fails to hit the correct angle, which causes the rocket to bounce off Earth’s atmosphere and fly into space endlessly. When it’s Liam’s turn, he successfully steers the rocket with more ease than anyone else, even navigating a meteor shower. Liam is sure he’ll get the votes again, but all the kids vote for Mr. Xanadu over fears that Liam will hog the console on the flight into space.
Liam watches Florida get ready to leave for the crew quarters and keeps asking if she’s okay, not wanting to admit that he’s worried about her going up into space. When Liam returns to the bungalow that night, he feels completely alone and decides to call his mom. She answers, but is confused as to why he’s calling in the middle of the night. Liam doesn’t realize until he’s in space just how lonely he can get.
All the dads are asked to fill out waivers so that the company can’t be held responsible if anything goes wrong. Dr. Drax keeps insisting that nothing actually will go wrong, but Liam starts to get a terrible feeling. He knows that Mr. Xanadu has no space-related skills and knows little about space, and hearing that Dr. Drax’s daughter won’t be on the mission makes it all sound even worse. When Liam hears about the possibility of a meteor impact, it’s all he needs to say he wants to withdraw his consent, but Dr. Drax tells him it’s too late.
The story’s rising action deepens the novel’s theme of Growing Up and Becoming Responsible, showing how Liam grows into his role as a leader and caregiver. Unlike the real dads, who rely on bribery, logic, or pressure, Liam understands what the kids need emotionally. He’s the only one who can get Florida onto the terrifying Vortex ride, not by coaxing or rewarding her but by believing in her and offering support. Likewise, he convinces Samson Two to participate, while Max’s father insults him and Hasan’s dad tries to get him excused.
Liam’s ability to inspire others helps develop the theme of The Importance of Fatherhood by showing that being a good father, or leader, requires emotional intelligence and empathy. At the same time, Liam learns that growing up means putting others first. He begins accepting his growing responsibility in earnest after he succeeds in inspiring others to follow his lead, especially in light of the challenge of each task. Liam continues to mature as he discovers that he can lead, and also that he cares deeply about the people he’s responsible for. Florida, too, begins to evolve, showing an unexpected interest in science. She begins by learning about buoyancy during swimming and then understanding gravity during the parabolas (zero-gravity simulations). This growth makes her more than just a side character; she becomes dynamic and multidimensional.
The other children reveal more complexity as well. Hasan shares a story about how his father bribed soldiers to keep him safe during a war, which explains his father’s obsession with money and safety. Liam’s moment of disappointment when Max votes for him only because he’s a “loser” who keeps things light suggests Liam’s desire for genuine respect. Though Liam repeatedly proves himself physically and emotionally capable, no one else seems to see it yet.
At the same time, the setting becomes more surreal and intense as the group undergoes physical and psychological tests in preparation for the space mission. One of the most vivid moments is the Vortex ride, wherein the trainees experience 15g, and Liam feels like a thought lasts forever. The strange, dreamlike nature of the experience emphasizes the line between thrill and fear. The setting amplifies the story’s tension, as the high-tech simulations, physically punishing rides, and secrecy surrounding the mission create a sense of suspense and unease. Dr. Drax, once considered eccentric, begins to show signs of manipulation and lack of empathy, especially when she refuses to let Liam withdraw consent for Florida to continue. Her denial of risk becomes sinister, hinting at a shift in the story’s tone from light and fun to morally ambiguous.
This section builds tension rapidly as it becomes clearer that the mission may not be as safe or ethical as it initially seemed. Liam is again the best performer during the parabolas, but he still doesn’t win the vote. He later excels in the flight simulator, managing the controls better than anyone else, but the children vote for Mr. Xanadu instead, fearing that Liam is too good and might hog the experience. These ironic twists deepen Liam’s frustration and isolation. The simulator itself foreshadows the actual space disaster: Max slightly misaligns the ship, causing it to bounce off Earth’s atmosphere and fly into deep space. This is exactly what happens later.
The novel continues to balance humor and dread through its distinctive narrative voice. One standout moment of dark humor occurs when Dr. Drax tries to comfort Liam by noting that the rocket is bulletproof. Liam responds with, “Bullet proof? Why would it need to be bullet proof? Does the man in the Moon have a shotgun or something?” (242). This line is both absurd and thought-provoking; it mocks the situation’s seriousness while hinting that danger is far closer than anyone is willing to admit. The use of irony and sarcasm, especially in Liam’s inner thoughts, maintains the novel’s playful tone even as the dangers increase. In addition, these literary devices convey Liam’s deeper anxieties and emotional conflict, showing the divide between his outward performance and inward fear.
