Re: Cold Shisha
I have tried smoking cold shisha before, for the same reason you have. The smoke is wispy because the coal takes a long time to get it up tot he right temperature in order to vaporize the glycerine and such.
This may sound stupid, but i would reccomend microwaving it... i did it and it worked fine. 5 second intervals, stirring every time. About 30 seconds, but if you go over the glycerine will become very thin and smoke harsh for a while.
