Enterprise Tackle Pop Up Sweetcorn is a buoyant rubber imitation grain of corn. It is soft enough to be used on the hook if desired, but is best when used on a hair rig along with real grains of corn, of a corresponding colour. Individual grains vary slightly in buoyancy, to allow a bait to be either critically balanced or popped up, depending upon the size and quantity of grains used. As a guide, 1 grain will just pop up 2 real grains of corn on a size 10 specimen type hook
