Can I hear you say “amen”

(Amen!)

Say it again

(Amen!)

Stone, stone, stone

(Rock!)

Primarily

(Sedimentary)

Specifically

(Porosity)

Stone, stone, stone

(Rock!)

Roll away the sandstone

(Holey rock)

Roll away the limestone

(Holey rock)

… and roll

(Amen!)

Ya can’t get blood

… from a stone

Stone, stone, stone

(Rock!)

Solid as a rock

(Yet floats your boat)

A mental block

(Learned from rote)

Preferably

(Permeability)

Stone, stone, stone

(Rock!)

Roll away the sandstone

(Holey rock)

Roll away the limestone

(Holey rock)

… and roll

(Amen!)

Ya can’t get blood

(… from a stone)

Take my word

(Pull the sword)

From the… (Rock!)

Roll away the stone

(Holey rock)

Roll away the stone

(Holey rock)

… and roll away

(Say:)

Amen!

The most porous rocks are typically sedimentary rocks, with sandstone and limestone being prime examples. Some volcanic rocks, like pumice, are also extremely porous due to trapped gas bubbles during formation.

* Sandstone: Often highly porous, allowing it to absorb liquids. The porosity can range from 11–32%.

* Limestone: Also very porous and can readily absorb liquids, though its porosity is often less than sandstone.

* Shale: Can be porous (8–29%) but often lacks permeability, meaning the pores are not interconnected.

* Pumice: This is a very lightweight, porous volcanic rock that is created when gas-rich lava cools rapidly. It’s used in many products because of its absorbent nature.
