Get a glass wine bottle chop the bottom off and use it as a gravity bong. You can find a little metal cap cantcha?
Ok guys I just used the pipe and it worked great. The reason why it worked great was because the bowl was faraway from the plastic itself so the plastic did not melt. The hot glue got a little warm and soft, but it would have never gotten hot enough to become undone and definitely not hot enough to burn the plastic one bit. I was shocked how much the carb hole worked and overall, it was a pretty successful toke
