What is the knowledge of Aluminum Hookah Foil and Wind Cover?

Hookah Foil
A hookah foil is a thin piece of aluminum that covers the bowl to prevent ash from entering the bowl. It also helps keep the heat from the charcoal in the bowl and distributes it evenly throughout the shisha tobacco.
The foil can be punctured with holes so that air can pass through the foil and tobacco. This lets air vaporize the tobacco to add flavor to the smoke.

Heat Management Devices and Wind Cover
Using an inexpensive heat management device will significantly increase the quality of your hookah session by ensuring that more heat is retained inside the bowl. This will help your charcoal pieces not burn out too early, which means you can enjoy a longer smoking session and a much more dense, flavorful, and voluminous smoke.
Another inexpensive heat management tool is an aluminum wind cover. A foil wind cover is similar to a DIY heat management device in that it protects the charcoal in the hookah bowl from wind interference and limits the airflow into the bowl, which makes your charcoal pieces last longer.
To use an aluminum foil wind cover, you need a longer and wider sheet of foil than the typical square or round foil. The foil should be 12 inches wide and a few inches taller than the height of the bowl. Then, fold the aluminum foil into a triangle at one end to lock it in place when you wrap it around the bowl.
