Did all the materials absorb water Why?

Answer: The reason it is soft and squishy (and the reason it absorbs water!) is because of all of the holes inside. These discontinuities in the bulk material are called pores. With the combination of driving forces discussed above (the reason to absorb) and porosity (the space to absorb) you have absorption.
