This is a high-strength container used to store helium gas, which is critical for pressurizing the rocket’s propellant tanks and ensuring proper fuel flow to its engines.

To prevent damage from acid and microbes, conservators usually remove water from these artifacts by freeze-drying or using a process that replaces the water with highly pressurized carbon dioxide or a viscous polymer.

Methanol is also a good carrier of hydrogen, which is hard to pressurize and dangerous to transport.

They then developed a suite of mathematical models to describe the mechanics of the pressurized fruit, the stem, and the ballistic trajectories of the seeds.

Stephen, recruited for his ability to provide the necessary tools, had produced a 100-tonne jack, explosives, and a thermal lance, which heats and melts steel with pressurized oxygen to create very high temperatures.
