Re: Scalli Mod..
the mod is used so you can used antother type of shisha in a tangiers phunnel bowl. this mod closes off the large hole in the middle of the bowl, phunnel that is, and forces the hot air to be pulled down under the shisha and then buck up underneath the coverd hole in the bowl, due to the mod. this also lets you use less shisha in the bowl. if im wrong about this im sorry but im pretty sure that is the reason for the mod.
