How to Make a Bong
To make a Bong is very simple, and u dont need pipes/bowls/tubing to make a bong and to get an excellent hit from a bong/
This type of bong may seems very bodged or unprofesional but belive me u get a kick out of it like nothing else
What you need to make a bong is........
Drinks Bottle (anything from 25ml +)
2 straws(kinda thick straws)
Tape
Water
Sciccors
Something sharp to peirce holes in(ScrewDriver is        good)
Dope(In the form of a joint (quite thin    rather than a fat marley)) - if you cant do this yourself i highly recomened    a rolling machine!(Or look here)
First step to make a bong would be
Take your bottle and pierce 2 holes in the bong/bottle

-----------------
So that one is slighty above the other. You want the wholes to be about the size a pensil or screwdriver this is so that the straws will fit nicely into your bong.Do not make any adjustmants at this point.
next step is to get your straw and to place the 1st whole (the one lowest down on the bong) in at an angle so it is around 1-2cm from the bottom of the bong
(This is the part where u may need to      widen the wholes a little bit)
The get the second straw and place it in the second hole angle it up a little bit - only about 10degree's though, nothing exteme, but it should be above the half way level of the bottle.Make sure it is in the middle of the bottle rather than jammed to the other side of the bong
Now heres a crude drawing of the bong - i am no artist as u can tell, but u kinda get the idea.
Now when you suck the straw on the left you will notice that the water bubbles - As long as the lid is on the bong
Put the joint in the end of the straw on the right of the bong(the one in the water). - this is where u may need to slightly widen the straw but snipping it. But it should fit in perfectly.
Use tape to cover up all the slight air gaps - but if you have made it correctly they shouldnt be any.
To smoke this bong u do it slightly differnt to gause bongs, click Here to see how to smoke it.
On mine(strictly for tabacoo use only of course) I used a black tango bottle.      - but i found i could not see when the smoke chamber had filled up. So i cut      out a square near the top. and then coverd the square in clear plastic from      another bottle.
You may also wish to try the waterfall bong
That requires even less stuff that this one
