Pour cold water into the vase. This is the large glass container at the base of the hookah. Fill it enough to cover 1 inch (2.5 cm) of the metal stem, or slightly more. Leaving space for air is important to dilute the smoke and make it easy to draw on the hose.
Insert the hookah shaft into the glass base. Lower the shaft into the base, so the stem enters the water. There should be a silicone or rubber piece that fits around the top of the base to make it airtight. If the fit isn't airtight, the smoke will be thin and difficult to pull.
Connect the hoses. The hoses slot into holes on the side of the shaft. Just like the base, these holes should be airtight fits. Some hookahs seal the hole if there is no hose attached. On other models, you'll need to attach all the hoses even if you're smoking alone.
Break up the shisha and place it in the bowl. Fluff up pieces of shisha and drop them in the bowl. Press lightly down to make a flat layer without compacting the tobacco. It should stay fairly loose so air can easily flow through it. Fill the bowl nearly to the top, but leave at least 2mm (3/32 inches) of space above the tobacco so it doesn't burn
Cover with heavy-duty foil. Lay a piece of heavy-duty foil over the bowl, stretching it taut. Crimp it around the edges to secure. Poke several holes through the foil. Using a toothpick or paper clip, poke about 12–15 holes through the foil surface.
Light two or three coals. There are two types of coals used for hookah. Follow these instructions depending on which one you have:
. Quick light coals: Hold with tongs over a nonflammable area. Light with a lighter or match until it stops smoking, then wait 10–30 seconds until covered in light gray ash and glowing orange.
. Natural coals: Heat directly in a stove flame or on an electric burner, but never where ash could fall into the gas line or on a glass stove. The coal is ready once glowing orange, usually after 8–12 minutes.
Transfer the coals to the foil. Place the coals evenly ringing the edge of the foil, or even slightly overhanging the edge. A common mistake is to pile the coals in the center, which can easily char the shisha and create harsh, short-lived smoke.
Inhale. Once the bowl is warm — or right away, if you're impatient — inhale through one of the hoses. Your breath pulls air past the coals, causing them to heat up. If you pull too hard, the air will get hot enough to char the shisha, and you'll cough on a lungful of bad-tasting smoke. Pull with short, normal breaths. Smoke at a relaxed rate, pausing to give the shisha time to cool down.
