What compressed gas can be used in jet packs?
The Manned Maneuvering Unit, or MMU, is a jetpack used in space. It uses compressed nitrogen as a propellant. Nitrogen is an inert gas that in most cases does not react with other gases. However, any compressed gas could theoretically be used to push a person in space.
