Miranda Maynard recently told the Idaho State Journal. He sent it to the family group chat and we were doing our amateur detective stuff, trying to figure out if it was real. Miranda Fiiz told the Idaho State Journal.

Miranda Maynard — a 22-year-old BYU student who has been building with Legos since her early teens — completed the team. The siblings from Pocatello, Idaho, were the youngest contestants to compete on the show’s third season, which premiered Sept. Drew Maynard told the Idaho State Journal. And so that was kind of intimidating because you want to show that young builders can still build really cool things.

During each week of the competition, Lego pros Amy Corbett and Jamie Berard judge the creations and make the elimination decisions. For the Season 3 premiere, the teams were tasked with building a personalized spacecraft in under 13 hours. The contestants had to create a spacecraft that introduced them to the show’s judges and viewers. When completed, the entire model had to hang suspended by a single attachment on the Lego Space Station.

Miranda Maynard said it represented their small-town life of grabbing a big soda, hopping in the car and going exploring. At one point during the episode, the siblings discussed putting the soda shop name Fiiz on the rocket. As the siblings worked on their creation, they bantered with Arnett, who commented on their age and joked that they looked like they could be the leads in a teen drama. NASA astronaut Jessica Meir later made a surprise appearance and announced that the winning creation would be displayed at the Kennedy Space Center in Cape Canaveral, Florida. When the countdown reached the five-hour mark, the contestants got to video chat with NASA astronaut Thomas Marshburn, who was aboard the International Space Station.

In the final 10 seconds, the teams hurried to get their creations attached to their own space station. And then it was time for the big reveal. The build was one of the largest models of the episode, and the judges praised the firefighters for their technical skills and for taking such a risk. Maynards for their creativity, but criticized their bottle rocket design for keeping their family’s stories and activities hidden inside. The judges said the siblings could’ve revealed more on the rocket’s surface.
