Answer 1

Is a grape a solid? Is it *more* or *less* solid than a raisin?

A raisin is 15% or less water, and a grape is about 75% water. The difference in size is purely based on the removed water.

People, like grapes, can have physical structures that store a lot of water while having a relatively solid outer surface.
