Duct tape was used to seal ammunition boxes, fix rotor blades during the Vietnam War, and make quick fixes on the original space capsules.
Not to be confused with Duck Tape. Duck Tape with a "k" is a brand name of duct tape. Duct tape is make by many different companies and can be bought at the local hardware store, mega-mart (Target), and big box home improvement store.
What can duct tape be used for? I propose that we use duct tape as alternative fabric.
Some may go to extremes to make a duct tape prom dress, yes it is possible: http://duckbrand.com/Promotions/stuck-at-prom.aspx
But for the every day user, like myself, duct tape is handy for quick fixes. In my younger years, duct tape was this cool sticky stuff that I used to make an mp3 carrier, wallet, and even book covers.
