Put water in the base. Put shisha in the bowl. Wrap the bowl with foil. Poke a bunch of small holes in the foil. Put one of those charcoal things on top. Light the charcoal. Wait a few minutes for it to heat up. Smoke away.
You may be best going to youtube or somewhere for the mechanics of how to use a hookah and come back when you're ready to start playing with your own blends for it. Its something that may be best observed rather than described.
And by the way, what exact online resources do you guys usually use for getting your smoking pipes or hookah? Or maybe even shisha for the smoking? I'm not an expert, but it looks like here is (***PM @dale13h for a link***) one of the best online stores I could find about hookah. Any other suggestions from you?
