Scoria is the best answer, but under some circumstances, probably pumice
The small holes in scoria are primarily caused by the rapid escape of gases during the volcanic eruption. As magma rises to the surface, dissolved gases like water vapor and carbon dioxide form bubbles. When the lava cools and solidifies, these bubbles create the characteristic porous texture of scoria, which is lighter than other volcanic rocks due to its numerous air-filled cavities.
CFC's have caused holes to appear. They react with ozone and deplete it.
Many extrusive volcanic rocks contain holes, or vesicles, which have formed from gases trapped in the magma during eruption. As the lava cools and solidifies, these gases escape, leaving behind the characteristic holes in the rock.

Pumice forms when volcanic lava with high gas content rapidly cools and solidifies, trapping bubbles of gas within the rock. This process creates a lightweight, porous stone that floats in water. Pumice is commonly found near volcanic areas and can be produced during explosive volcanic eruptions.
When they have holes in them!
it is air pockets stuck in your brownie
Yes, you could say this. The holes, however, are irregular and could be described as pockets.
Holes in igneous rock are typically caused by gas pockets or bubbles that were trapped within the molten rock as it solidified. These gas pockets can be created by dissolved gases escaping during cooling or by volcanic activity that releases gas into the molten rock.
In early drilling of holes in glass garlic was used.

Pumice
Some dress shirts commonly have holes, which are pockets. The pockets are just a apart of the shirt for stylish accent.
The fluid just settles in the pores (air pockets/holes)of the material.

The holes may be button holes, air holes, or holes caused by damage to the shirt.
The holes in the wall were caused by someone or something damaging the wall, such as punching or drilling into it.
