My friend used to do it with a Gatorade bottle and like a big plastic sports water bottle. Personally I don't like smoking those things but to each their own.
get a large bottle with the top cut off, and a slightly smaller bottle with the bottom cut off which fits inside the big one, fill the bigger one with water when you set it down to toke.
I'm actually going to post a tut, on this tommorow. It's a waterfall gravity tho.......still does the trick tho.
Okay... You'll need 2 water bottles... And a makeshift funnel.. Take one of the 2 caps, and fashion a bowl into it in a way that it still screws on to the bottle(A)... Take the bottle(A) that cap came off of, and burn a half inch sized hole on the side, very close to the bottom. So now you wanna smoke... you plug the hole(A) with a finger... and fill the bottle(A) up with the other bottle(B).. It's best if a friend helps but it is doable alone. Put the funnel in the now empty bottle and set it on a table or something. You'll light the bowl and remove your finger from the hole(A) allowing the water to fall into the funnel. When it's done draining, take the bowl off, breath in the smoke. And repeat as needed.
