You can wacky rig a tube by stuffing it with a piece of plastic worm, then going to the hardware and getting some O rings that fit snugly over the tube....slip the hook under the O ring for a wacky rig. If you need weight, slip a small splitshot into the tube before inserting the plastic worm piece. If you use a different color worm than that of the tube, use a hand held paper punch to punch a whole clean through the sides of the tube near the front end, then when the worm is inserted, you will have made eyes the color of the worm. Just remember to leave a little room at the very front for weight. If you want a very slow falling tube, leave an air chamber at the front end of the inserted plastic worm. I trim the worm after inserting, just where the tube skirt begins.
