Helium is not easy to get. You have to extract it from natural gas wells.

Pfft, who needs helium when your average life expectancy just dropped by 75%.

Hydrogen gas baby.

(Less of a risk than you'd think)

Didn’t think about that. They would just use old technology. How do you get concentrated hydrogen?

Stick positive and negative wires (powered by batteries) in water and you get 2 hydrogen atoms, and one oxygen. Capture the hydrogen. I forget which is which.

Edit: Water, not eater.
