eli5 – How can the human body be composed of 70% water when it feels and behaves like any other solid?
In: 18
Take the amount of water that’s inside a human body and just pour it all into a big bag. It sloshes around a lot and feels like a liquid, right? Your question is asking why people *don’t* feel like that.
Well, take all of that water, and split it up among several billion teeny tiny boxes. Put all those boxes together in the shape of a human, and it’ll contain the exact same amount of water as the big bag did, except now it’ll feel solid because the water is all held within objects which have shape and structure.
In an actual human, those billions of teeny tiny boxes are all of the cells in the body.
