best gravity bong ever! cheeep!

ive recently started using the gravity bong and trying to make it better and better. i think ive found the best, cheapest, and easiest way to make a bong that can concentrate smoke so dense that one hit will fill a room with haze.
what you need!

1. 1 gallon plastic pitcher(wide enough for the bottle)
2. empty 2liter bottle
3. 9 inch or longer glass downstem
4. matching bowl
5. electical tape(be ready to use about 1/4-1/2 roll)
6. water and ice!

1. i just used what i had, ended up being the perfect size. dont expect to reuse this container without much washing, a resin film will develop and ash will float around on the water.
2. its the perfect size, anyone who thinks they can clear it when its yellow-dense is clueless. that one hit will FLOOR you. cut it at the bottom, theres a line in the plastic at thats the perfect spot. be careful and remember "CUT AWAY FROM YOU!!"
3. i got the glass downstem at the local shop, it was 4$, 9 or 12mm id i forget, but it matches the bowl for my bong. perfect.. 9 inches is the minimum length you want to go, any shorter and you may not bubble as much as you can.
4. theres really cheap bowls, 5$ glass is all you need
5. no gromits for this yet, but electrical tape is a good sealer. you NEED to have a airtight seals, it is VERY important for a good gbt. i mark the 2 liter by setting the stem and bowl up and pull up and mark where the air will start to flow. you have to be careful not to pull to bottle all the way out while burning a bowl, it will ruin the hit. and anything but green hit on this bong will HURT you!
6. water and ice, colder the better. the smoke will give you shivers is comes out so cold! put 2 trays of ice in the bottle so it bubbles through the ice :thumbsup:

danm.... eeeeeeeeeeeeeeeeeeeeeeeeeeeeee oops

I made one of those with my friends back in 8th grade but we used a trash can and one of those big ass water jugs (like from a office water cooler thing). We would fill it with smoke and everyone sat around it in a circle, we could go around a couple of times before we would clear it. Always wanted to make another one but dont got a big water jug.

i made a gravity bong not too long ago, 2 hit got me TOO high and I HAD to lay down and sleep or i was gunna throw up. That was a bad experience.
