Re: Quick Hookah questions
Speel's answer pretty much covers it.
I would like to add a little to his answer on knowing when your shisha is done.
After you are a good 30-45 minutes into it the smoke will thin and eventually not come out at all. This is usually the biggest tell-tale sign that your bowl is finished and that it's time to repack.
And as for clean up. I like to get rid of the coals first and then proceed with the clean up.
Hope this answer helped...
