Berkley Powerbait Sparkle Power Eggs is a liquid egg, with the fish-catching scent Powerbait. This egg is incredibly good for rainbow fishing in ponds and lakes. If you fish the egg as it is, we think a bottom angler works best, if you want a float angler then try to make a "cocktail" with a worm. Then the worm weighs down the egg and gives both life and movement. Sizzling hot!
