You need to store duct tape. Duct tape has many uses, on Mythbusters they even built a boat out of it. Now I am not advocating that you build a boat from it. But it does have hundreds of uses; whole books have been written on them. I have used it for a temporary fix on radiators hoses and to repair tennis shoes. I came home one day and the door of the freezer was taped shut. My wife explained that she had shoved so much food in the freeze the door would not stay shut so she taped it shut. It can be used to repair clothes, backpacks almost anything. I always carry some of it in my backpacks and vehicles. You can even twist it together to make a rope.
Duct tape was created during World War II when the US military needed a flexible, durable, waterproof tape to use making repairs in the field. As the story goes, the GIs called it “duck tape” because it was waterproof – like a duck’s back. Somehow, the name has evolved to duct tape.
It is carried by all the paramedics around here, who use it during rescues for anything from compression bandages to taping someone to a backboard. If you have to shelter in place with a sheet of plastic and some duct tape, you can improve your chances of survival. I know the press laughed at the duct tape and plastic idea. However test conducted by both the US and Israeli governments proved that it does provide a level of protection from chemical and biological attacks. Here is a link to a site that provides addition information on the subject http://www.fas.org/irp/threat/duct.pdf.
Duct tape comes in three different grades, Industrial, Professional and Premium. Industrial is the most common and the least expensive. The better grades of tape are thicker and have greater holding strengths. The industrial grade is good for most uses, but you may want a few rolls of a better grade.
Just beware that some of the duct tapes from China are of very low quality, buy the best that you can afford. You can never have to much duct tape.
