Porous objects.

Porosity is the property of an object that expresses the total volume of empty or pore space in the material. For rocks that contain hydrocarbon resources, porosity measures the percentage pore space occupies in a rock. [2] A porous rock contains a large number of tiny spaces, which allows it to hold oil, natural gas or even underground water! [3]
