Re: Sambuca tasting tobacco?
Good luck, don't put too much though! I made the mistake of putting too much alcohol and it tasted like I was smoking Jack Daniel's flavored shisha, which wasn't too bad, aside from the fact that it made my hose and base smell like whiskey for days.
You have to be careful though; you absorb alcohol through the lining of your lungs a lot easier than you do by drinking it so you will get buzzed/drunk if you smoke enough. It is dilluted heavily by the water, but still, better to be safe than sorry.
One good thing though is that since alcohol has a significantly low freezing point compared to water, you can substancially cool down the water in your base by adding "super chilled" alcohol to your base. It just has to have been sitting in the freezer for a few hours. But then again, salt water works in the same way and is safer :P
