nah it doesn't matter how big your gravity bottle is, the smoke the in the bottle doesn't overflow or something lol.. i use a little powerade bottle and put it inside of a 2 liter bottle cut in half filled with water as a "bucket" and use a socket for the piece cause they're perfect lol.. the one i use is pretty big.. teh bottle fits in the 2 liter perfect so it doesn't fall over into the water, so you can let go of it :P lol and pulls killer gravities.. and it's portable as shit, i've been on "gravity rides" with that thing lol.. usually people don't clear em in 1 inhale.. but it's def the perfect gravity, it's all i usually smoke out off lol.. but if you wanna use a bucket, i use a apple juice bottle or like a cranberry juice bottle cause they got big caps to put a big ass socket on it.. usually 1 gravity and your high so it's nice lol.. HUGE ass headchanges when you take the whole things, you def need to recover after a hit lol
