The holes may be button holes, air holes, or holes caused by damage to the shirt.
Through the many holes in the leaves called the stomata.
The type of rock that has small holes filled with sugar-like crystals is known as geode. Geodes are hollow rocks that contain mineral crystals lining the inner cavity, often formed when minerals dissolve and recrystallize within the rock's open spaces. These crystals can resemble sugar in appearance, making geodes popular for their unique and beautiful formations.
Clouds are air masses filled with tiny water droplets or ice crystals.

Opening the air holes increases the amount of air mixing with the gas, resulting in a hotter and more efficient flame. Closing the air holes reduces the amount of air mixing with the gas, leading to a cooler and less efficient flame. Adjusting the air holes allows for better control of the flame temperature.
The flame will start to weaken and eventually go out as you cover the air holes. This is because the flame needs oxygen to sustain combustion, and by covering the air holes, you are restricting the flow of air needed for the flame to burn.
