A propulsion system for a projectile launcher may comprise a propulsion source, the propulsion source having a first end, a second end opposite the first end, and a propulsion source wall. A puncture structure having a fluid channel may be located proximate to the first end. A puncher may be located proximate to the second end and configured to translate the propulsion source from a first position to a second position. Translation of the propulsions source from the first position to the second position may fluidly connect the fluid channel and the propulsion source. The projectile launcher may be activated upon the propulsion source being fluidly connected to the fluid channel.
