Glass Water Pipe "Won't Work" Okay, I GET that this is a n00b question. i know how to use glass pipes, but i recently got a bubbler. it looks something like this http://img.alibaba.com/photo/11441992/Glass_Bubbler.jpg now, i smoked out of it only twice, and it was working well. then, i tried it a third time and when i took my thumb off the carb and inhaled, it was met with resistance and NO smoke entered my mouth... i cleaned it three times, each time using a successful method of cleaning, but nothing has worked. so Rating: 5
