Take any tube style bait, break off a small piece of alka seltzer or any oxy tab and push it clear into the top of the tube head, follow this with some power bait or any smelly stuff or velveeta or what have you and watch the action. Fish it slower than normal. The bubbles give off noise and a sight trail as well as a heavy scent trail from the bait. Team this with a dying twitch and quiver retrieve and prepare to be impressed. Have caght a multitude of different species using this trick. I figured I better pass it on or end up taking it to the grave with me someday.
