dont use tinfoil....get a small socket wrench set and make one from them....or take one from your dad if he has a socket wrench set. it gives you a nice small bowl put it in a large gatorade or 2 liter cap and boom instant bong.

put one of these bad boys in the cap, http://www.istockphoto.com/file_thum...socket_set.jpg cut the bottom off the bottle right at the nubs or feet, and get a plastic bucket or pitcher add water and enjoy....the sockets are usually steel and you can get a cheap set at walmart for like 5 to 10 bucks and you got enough to make 10 bowls
hammertime Reviewed by hammertime on . 2 liter gravity bong take a two liter and poke a hole at the bottom, put tinfoil and weed in the cap part, after youve filled the 2 liter with water and have you finger over the hole. Light the bowl and remoe your finger and the bottle fills up. is that easier than a regular gravity bong? Rating: 5
