Question: how do you get an alien baby back home?

Hypothesis: If four teenage girls go into the weird space portal, then alien baby's mom-or-parent-or-amoeba guardian will not start an intergalactic war and the portal will close

Experiment: go into portal, fix everything, and DON'T DIE

Materials: Water bottles, two walkie talkies (do walkie talkies even work on an alien planet?), alien baby that came through weird space portal.... and headphones
