Well, i found a patent for it. It seems that there is shisha included inside of the bowl. I doubt someone has maed this, but it seems like it could come in handy for using when you want something portable. Cause honestly, when i go on a nature walk and bring my hookah, i hate getting my fingers stick from the shisha and i am scared that the bowl will crack. Its a good idea, but too much might need to be implemented for it to be useable/profitable.
