1)Take a big plastic bottle as mentioned above(the bigger the better)

2)Cut off the lower part about 3-4 cms from bottom

3)That bottle probably had a lid goin with it(they do that a lot dun you think?)...cut the covering part so that you're left with a ring(the screwing part only)

4)Shape a few sheets of aluminium foil into a bowl and put some holes in the bottom with a needle(dun make them too big)

5)Stick your "bowl" through the ring you made out of the bottle lid and make sure that it won't go through all the way fallin from the other side!

6)Screw the whole thing back on the bottle

7)Pack the "bowl" with some good uknowhat

8)Take a big bucket full of water

9)Now slowly put the bottle in the bucket bottom first and gently push it in(otherwise the air being pushed out of your "bowls" holes by the water below will blow your shit out of the bowl and make for an unecessary fuss) till the whole of it but the lid is submerged

10)Light up the bowl

11)Slowly start pulling the bottle out of the water with the bowl still lit...the bottle "inhales" and is filled with smoke...pull out until only a few mms are still submerged or until you're satisfied with the quantity of smoke that's been built up in the bottle

12)Unscrew the lid and shield your lips around the lidhole...

13)Push the bottle back into the water fast while you inhale through the lidhole...

14)Find somewhere to sit or lay down asap!!!
