If you're new to hookah smoking, you may be wondering what hookah foil is and why you need it. Hookah foil is a thin sheet of aluminum that is placed over the hookah bowl to help keep the heat in and prevent ash from entering the bowl. It also helps to keep the tobacco moist so that it doesn't burn too quickly. Many hookah smokers prefer to use foil because it provides a consistent smoking experience. When using foil, be sure to poke holes in it so that air can circulate and the tobacco can flavor the smoke. If you're looking for a great hookah smoking experience, be sure to give hookah foil a try!
