The hallmark of the popping cork is its distinctive sound. Snap the rod tip and the float goes “pop-pop.” The lure rises then falls tantalizingly, the fish investigates the sound, sees the lure and eats it. Most rigs have wire harnesses extending through the float. Various arrangements of plastic and/or metal beads sliding on the wire strike the bottom and top of the float when the line is pulled, imitating the sound of a shrimp flipping its tail. Simple Logic makes using a four Horsemen Popping Cork a no brainer.
