I've been watching some tutorials about the best ways to fill cartos. So far I've seen people use the condom method, syringes, plunging with tubes attached to syringes, and dripping.
They all look effective enough but one thing confuses me. I thought it was necessary to keep the juice out of the air hole that runs through the carto (the tube surrounded by filler material). Except for dripping, most of the videos show juice coming up this hole or with sucking juice through the carto the whole thing being saturated. Do I really need to keep juice out of this hole or are the people making the videos getting the juice out somehow off camera?
