Shirtbloke, are you saying that if you cutoff the ends of a Q-tip, the center is hollow? Like a straw?
I have one needle tip bottle, and it is a lot more useful than the standard drip tip. That seems like a very useful hint.
I had to try this as soon as I read it. Q Tip stems are tightly rolled paper, and there is a small space in the middle. It might be good for a drip tip, but refilling a clearomizer would be out of the question, as juice comes out so slow. Also, if you squeeze the bottle too hard, the Q Tip stem can fly out, along with a good amount of juice.
