The hookah double bowl is an excellent gimmick for starters, and can be pretty useful. Imagine your self having guests for a hookah session, and having to get up and replace the bowl content every few minutes. Isn't that a drag?

Now imagine, that you can fill two bowls with tobacco, seal both with an aluminum foil, and use only one of them. When this one is out, seal it again with a new piece of aluminum foil, and start up the second one. Now stop imagining, and go get yourself a double bowl!

The double bowl is available in every hookah shop online, as: http://www.smoking-hookah.com for 10$.
