If you want less air flow try covering the bottom of the bowl with a piece of tin foil first then poke only a couple holes in that, put your stuff in, and cover it again

I was gonna try this sometime, let me know if you try it
SunnyD Reviewed by SunnyD on . Question about Hookahs When you smoke out of a hookah does it basically act as a vaporizer since the coals on top merely heat the substance underneath the tin foil, or does it cause the substance to combust? trying to decide on whether or not I want to buy one A friend of mine just got one this week and it's pretty nice. Curious as to whether or not smoking out of a hookah is better for you Thanks Rating: 5
