Gem Drill (object)

The "Gem Drill" is a subterranean drill built by the Crystal Gems with the purpose of drilling to the core of the Earth and stopping the Cluster. It first appeared (as several uncombined components) in "Too Far".

Appearance
The drill's physical design is rather straightforward. It's main components are an old injector drill head and Peridot's escape pod joined together at the drill's shaft. The escape pod serves as the cockpit for the pilot of the drill.

"Back to the Barn"
The Gems brainstorm and come up with a conclusion that they need to build a drill to dig into the center of the Earth to save the world from the Cluster before it hatches.

"Too Far"
Peridot and the Gems officially start building the drill. The base for the drill is an Injector drill head from the Kindergarten. Peridot accidentally starts the drill head and almost injures Amethyst, destroying everything that the Gems had worked on so far.

"Steven's Birthday"
Whilst Garnet, Amethyst, and Pearl celebrated Steven's birthday Peridot continued working on the drill.

"It Could've Been Great"
The Gems and Peridot finally finish its construction, and all they needed was the exact coordinates of the Cluster. They travel to an abandoned Gem Moon Base to find them.

"Log Date 7 15 2"
The drill is shown under construction during flashbacks. Peridot is seen programming the escape pod with a computer. Amethyst and Pearl fuse into Opal, who picks up the drill head and sets it on some supports.

Trivia

 * It is first mentioned in "Back to the Barn" that the drill will need to withstand up to 360 gigapascals of pressure and temperatures up to 9,800 degrees.
 * The drill uses a drill head from an Injector once used at the Kindergarten.
 * Pearl jokes that the technology that started the Cluster crisis is now going to be used to end it.
 * According to Peridot, the drill is composed of mostly carbonite. In real life, carbonite is an explosive mixture used in mining. However, in fiction, it is the metallic substance used to freeze Han Solo in the Star Wars franchise.
 * The microwave from the Beach House has components used in the drill, especially its magnetron.
 * Magnetrons are also found in old radar technologies, which may explain the Gems' use for it.
 * Tungsten, a component for the drill, is known for having the highest melting point of all pure metals, being this 3,695 K (3,422 °C, 6,192 °F).
 * Also, this material has an elastic modulus (force needed to temporarily deform an object) of 400-410 gigapascals, being one of the highest among any known material.
