Re: Not quite sure what I did wrong...
I guess it's possible there was a leak. The suction on my hand was pretty weak-- the hookah was delivered fully assembled so I'm not sure if anything was loose besides the hoses and the stem/bowl (I made absolutely sure those were air tight). I might just disassemble it and do it again myself since it probably did get jostled around when it was delivered.
Yes, I did watch your video =D It was the easiest one to follow along with. Most of the other tutorials I found just confused me, because they were giving instructions as if they were talking to seasoned smokers and not a beginner such as myself XD
