Babies
According to a cartoon I watched once, here’s a recipe for making your own babies. Water (35 L), Carbon (20 kg), Ammonia (4 L), Lime (1.5 kg), Phosphorous (800 g), Salt (250 g), Saltpeter (100 g), Sulfur (80 g), Fluorine (7.5 g), Iron (5 g), Silicon (3 g) and fifteen traces of other elements (Whatever you got laying around I guess). You can probably get about 20 babies from this recipe.
