If you're looking to enjoy a hookah smoking session, you'll need to purchase some hookah foil. This specialized type of foil is designed to fit snugly over the top of your hookah bowl, and it helps to keep the coal in place while you're smoking. Hookah foil also ensures that the heat from the coal is evenly distributed, which leads to a better smoking experience. Furthermore, hookah foil helps to prevent ash from falling into the bowl and ruining your tobacco. So if you want to enjoy a hassle-free hookah smoking session, be sure to pick up some hookah foil before you start.
