(at around 53 mins) When the children are in the gyrosphere watching the instructional video by Jimmy Fallon, he mentions the sphere shell is comprised of "aluminum oxynitride" for enhanced durability (a.k.a. transparent aluminum). This fictional material was originally popularized in Rotta verso la Terra (1986), and was an engineering staple in the twenty-third century for its remarkable properties. A single 60x10 foot sheet could withstand the pressure of 18,000 cubic feet of water while being only one inch thick. Ironically, aluminum oxynitride was recently invented. It is comprised of aluminum, oxygen, and nitrogen, and is commercially used as heavy ballistics glass armor protection. It can stop a .50 caliber armor-piercing round.
