Marsh Works has added the cup-faced Chugger to its popping-cork lineup. All Marsh Works corks feature heavy stainless wire (30 percent heavier than comparable brands, Marsh Works says) and all brass and glass components. The glass bead at the bottom of the cork adds sound volume and weight for casting. Chuggers weigh 34 of an ounce and come in fluorescent orange, pink and yellow. Packaged individually, they cost $3.49 and are made in the United States. Visit www.marsh-works.com.
