Sorry I don't have it any more so can't make a instructable on it! If I get ducttape any time soon I might make other one then I maybe post instructable on it.
per haps taking a water bladder and coating it in duct tape would work. i did a similar ible here http://www.instructables.com/id/Duct-Tape-Hydration-pack-on-the-cheap/
Canteens are for water, not food. And it'll be fine if you wash it out and have no sticky on the inside. It was made for waterproofing ammunition crates in WWII, and would work absolutely fine as a canteen.
I know what canteens are, and "food safe" is a general term. The USDA defines food as "a raw, cooked, or processed edible substance, ice, beverage, or ingredient used or intended for use or for sale in whole or in part for human consumption, or chewing gum" when discussing food safety. The bit that separates one side of the tape from the other is the adhesive, and the factories producing duct tape are doubtfully concerned about contaminants in the product since it was not intended to be used as a food or water container or to come in continual contact with the body. Waterproofing ammunition crates in WWII is not proof of food safety.
The canteen would make for a good prop or costume accessory, but it would be irresponsible to say that it was a safe container for drinking water.
You have a point, but I have a few sayings for you. 1.) I reject your reality and substitute my own. 2.) Live dangerously. Also, when I was talking about Ammunition crates, I was talking about the fact it's waterproof, not that it's food safe (no implicaton implied). And any contaminates from the Duct Tape would be washed out by water. I know it's probably not a good idea to use it repeatedly over a long period of time, but just to show it off every now and then, along with thourough washings and replacment every now and then, it would be fine for you. There are few problems in life a liberal ammount of duct tape can't solve, and this isn't one of them.
Some contaminants get leeched out slowly over time and not just from quick rinses which is partially why you use glass in chemistry experiments rather than plastic, and disregarding the health risks, I really don't think anything coming out of a duct tape container would taste good. You'd be suffering one way or another for a little bit of glory/fame when there are many other things you can do with duct tape for a similar amount of prestige. Best to buy a metal canteen and cover the outside with duct tape for cushioning, insulation, and customization since duct tape comes in a lot of colors and patterns.
You have a point about that, but I think it should maybe used in worst-case scenarios and for show. And I'm sure a few drinks from a duct tape canteen won't kill you.
