Wonder why its now Duck? Oh no...
One of the brands of the original was "Duck" with a picture of a yellow cartoon duck on the label, and the name became generic...
Star Wars fans all know that it is what they were referring to when talking about "The Force" - after all the stuff has a light side and a dark side, and holds the universe together....
In actual modern practice, one of the few applications where duct tape is considered totally unacceptable is for taping ductwork.... The changing air pressures in a duct system, plus the heat tend to rapidly dry out the tape and cause it to flex, leading to joint failure and air leakage. You are supposed to use a special sealing mastic tape for duct applications - looks sort of like tin foil with an asphalt glue....
