I got a glass hookah to smoke in the car while on road trips. I decided to go for an all glass hookah, but it smoked very badly at first (harsh and short sessions). I figured that the problem was the bowl, so I got a joint specially made so I could use a regular clay bowl. Now it smokes as well as my 28 inch hookah! Pics aren't working from my phone, so I'll upload some when I get to my PC.
