How does absorption work? Why is it that rubbing yourself with a towel mostly dries you off, but rubbing yourself with a banana or a rock doesn’t?

Question

Sorry if I got the flair wrong, I actually don’t even know what kind of science is at play here!

Answer 1

* Surface area.
* A towel has lots of tiny little fluffy threads and each one has some surface area and can absorb some water.
* A banana (as compared to a towel) is very smooth and so have a very small surface area to absorb water.
