Now I'm confused. If you plug the air canal that the liquid would go through with a toothpick when using the condom method, then how would the liquid get into the cartomizer stuffing? It makes sense to me to stick the toothpick into the inner whole of the carto after removing the two plastic peices on the mouth end, and then dripping liquid in via the mouth end. This way, the liquid would go directly into the stuffing, without any liquid getting into the air canal.
