hey guys .. just though Id tell you about something fun to do. Experimented with it after a few shots of tequila when i had some lemon rind left over. It seems that is you place a small piece (about the size of 2 corn kernels) of lemon peel between the charcoal on the foil, you get a nice flavour for about 3-4 puffs. Then you have 2 change it because it gets burnt. soo if u ever have a shot of tequila with your hookah ..you can try this ..
