"Actually, I'm not sure what else I can do with the lava." Senku admitted. "The rocks are quite useful, as rocks they're not like sugar exactly, they have a harder density than sugar, and could make good tools or something like that."

He sighed a little, and held out the bottle. "Here, but that's all the lava I have, don't give yourself a stomachache."

"The shells, I'd like to see if they're made of calcium carbonate and if that works out we'd have some of that on hand, wicked useful that it is. And then this..." He held up the berries. "Another thing I'm not sure what to do with. We could make wine? It would be a very small batch though. Not wine exactly, some fruit based alcohol."
