i did this in the soviet installation. just find a can laying around and hold
to make a shrapnel grenade. this will cost you 1 Magnesite Ore. now look around for some small animals. there is a spot near the buildings where birds will repeatedly spawn. sometimes you will notice there are no animals when you enter an area. if this is the case, use fast travel to leave and come back.
note: i tried using a lantern on a rat and it didn't work. i guess a lantern is just fire, not an explosive, so gas cans probably won't work either.
