Alright...

1.) I would just make a bong out of a water bottle. They are extremely cheap to buy, easy to make, you can just throw it away when you're done, and it will lure you because of the hugeass rips that you can take out of it, and your friend will like it because he can control the size of his hit and it will hit smooth and cool. Go to "everyonedoesit" (the link is in my signature) and check out the video on how to make one.

2. You're going to want to use more weed than hookah tobacco. The hookah tobacco is just there to slow down the burning process a bit and make it taste nice.
