Fill the glass base of the waterpipe with water. Make sure you don't fill too much. You should fill enough to approximately cover the tube from the top section by about an inch when it is placed over the base.
Place the heart (top part) over the base (the glass vase). Make sure it fits snugly and is airtight. You may have to add gauze on the inside of the top section.
Attach the mouthpiece to the top section, again making sure that the joint is airtight.
Test that your setup is airtight by placing your hand on top of the waterpipe and then sucking in through the mouth piece.If everything is okay, you should feel a pull at your hand and see bubbles in the water.If either of these two things don't happen, then in all likelihood, you have air escaping from somewhere. Carefully check to find the source.
If your setup is airtight, place some of the tobacco on top of the water pipe .If you smoke a flavored molasses it is recommended to cover the tobacco by aluminum foil and pierced several times with toothpick.
Go outside and light your charcoal, you can get the self-lighting charcoal (especially made for water pipe, no kerosene add).
When lit bring the charcoal inside, holding it with a pair of tongs and place it on top of the tobacco.
Gently pressing down on the charcoal, suck in using the mouthpiece. You should notice smoke building up inside the base and eventually (after about 3-4 puffs); you should feel the taste of the tobacco in your mouth.
