Gravity Bongs

I've never used one but my roomate did (had to get rid of it before anyone else had a chance-wasn't subtle). Basically it really seemed to zonk him-he was getting flashbacks off shroom trips and the like-who has used one and are they any good?

if you do it right you get giant hits

They're easy to build, and they get you R I P P E D.

Def gonna be given a try in the not too distant future.

are gravity bongs the same thing as a waterfall bong? holy shit i fucking love waterfall bongs omg we made one and holy shit i almost passed out after two giant fuking hits

its the same concept as a waterfall bong but u basically force the smoke into your lungs, its easy to hurl off them cuz of so much smoke going into your lungs at once

one time me and my freinds made one and we were so amazed at how dence the smoke was getting in the bucket that we just kept toying with it. i smoked so much that i passed out on my freinds bed and couldent move i felt like i was glued to the bed

i'm going to make one

what should i use as the bowl....?

use the end of a coaxial cable line (The one that brought cable to your tv back in the day?)

Or, a ratchet head small enough to hold bud, but not drop it into the water. (Bud is ruined when wet.

For a good bowl look by the copper pipes in the hardware store. There should be adapters which change, say an 1/4" pipe to a 1/2". Puttin a screen in it is a good idea too.
