hmm from waht i read frmo KYA's post about his experience, i think ive experienced it too, although i never thought it was anything like negative ions or ozone.

my friend was cleaning her pipe, and she soaked it in a bit of alc, and then rinsed with water, and afterwards when we smoked, it kept making an almost popping sound, which sounds like what KYA is experiencing. I just assumed that it was still wet on the inside or something, and taht the heat frmo the lighter is just evaporating the liquid
BBoyShotty Reviewed by BBoyShotty on . bubbler makes ozone? I cleaned my little bubbler out today, and did a dry inhale, just curiosity I suppose. But I noticed a snapping, didn't sound quite like it sounds when burning some mary. But I smell the discinct odor of ozone directly afterwords. I've done it 10 times, so I know I'm not crazy. Can someone else with a bubbler confirm this? I googled it shortly, but didn't find anyone else saying anything about it. It required a little more wind than a normal hit(for me anyways), otherwise, there's no ozone Rating: 5
