With duct take you could; make clothes make a wallet make a bridge make a hammock tie someone to a chair fix a shovel hog tie a person save yourself from a nuclear attack eat it? decorate your house (they do make different colors) patch your roof patch a wall hold your car door on fix a leak in a hose make a tourniquet fortify your refrigerator I'm sure there is more but this is all I can think of for now.
i have a metal comp chair and one day it broke and it was in like 5 different pieces so what i do is grab the duct tape! i tape it all together and now i can still sit and tip in it, even tho it hurts my back
