Not sure if it's different now, but 15-20 years ago that's how mine and all my friends' looked. You could start with a clean one and it would be dirty as fuck like 3 hr later. We would just change the water a lot but only clean them every week or two.
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.
Nah I was just curious, I have a theory about why weed isnharder to quit when you're smoking, cause for me the cravings feel identical, so I'd either smoke a shit tonne or just go back, but mates who didn't smoke and smoked weed hard like me could just stop.
But fuck yeah man, thats wicked, yeah definetly not a race.
I recently gave up drinking, currently on the end of quitting nicotine.
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.
