Tom Ridge advised everyone to buy duct tape for bio and radiological protection.
Yeah, you should use anything but duct tape to seal ducts, but it works great on everything else. It’s good for automotive repairs, spacecraft fixin’ and many other things.
It’s so good, apparently “In Finland and Sweden, some folks (we are told) refer to duct tape as “Jesus Tape.”” I’ve heard that at NASA it’s called “engineering tape”.
Oh, I did not know it came in Beige, Black, Blue, Burgundy, Brown, Gold, Floral Green, Green, Olive Drab, Orange, Purple, Red, Silver, White and Yellow. Mmmm, purple duct tape.
