I don't think I've ever used duct tape for its intended purpose. Rather, the several rolls knocking around my garage serve to keep a broken freezer door sealed, a chronically crooked picture frame straight on the wall, and a well loved inflatable pool toy from leaking air. While repair purposes are the most common function for the household essential, duct tape has occasionally appeared as a star on the medical front as well. Survivalists praise the adhesive for its utility when it comes to preventing blisters or splinting sprains, strains, and fractures. A few years ago, duct tape also made a name for itself in the wart removal business.
