its not to hard my freind made me one the other day
You need a bucket thing that looks square like a sink and a milk container (the big plastic type) and some thing to use as a bowl
1st- you fill the bucket with water
2nd- cut off the bottem of the milk container
3rd- you cut 2 holes in the container need the top for the bowl and carb
4th- put the container in the water so that the cut of part is submerged
5th- smoke, by filling contaqiner with smoke then take off top and push container under water as you inhale so it pushes moke up.
so it is easy im sorry if i wasn't clear enough
