I came up with it years ago, its the only way to have buckets.
So you cut your bottle like normal, then you grab some hose, melt a hole in the lid and poke the hose out with enough room to fit a piece in, then screw that into the bucket, you want to cut the hose so its about an inch above the bottom or when you get a nice smooth bubbling.
You get the big hit of a bucket, but its way colder and smoother.
A gravity bong here is like a 600ml bottle with a hole burnt on the bottom big enough to let water through but still be covered by a finger or thumb, slow stead y stream pulls, kinda like a travel bucket.

A highly detailed blueprint:
This is a gravity bong. We made them with 2-L soda bottles in a 5-gal bucket (what can I say about our fucked up measurement system, I’m American).
