prob like a gravity bong (maybe never heard of them!)
You need 2 soda bottles (a 2ltr and a 3ltr is good) cut the bottom off the small one and the top off the big one so you get a snug sliding fit.
Place a bowl in the neck of the small bottle or use tin foil as you get a nice tight fit.
Fill the big bottle with water to about 4 inch from the top.
Burn your green while at the same time slowly draw up the bottle thus giving you a 2ltr brick of smoke. Remove the bowl pinch the sides of the small bottle to break the airtight seal (if it is airtight) then inhale the lot in one go as fast or as slow as you like.
Sit back and relax![Icon Lol :lol: :lol:](/styles/default/xenforo/smilies/icon_lol.gif)
