I started thinking about rope recently after Mr. Balleng
posted his rope making instructable
. I also remembered this old instructable in which they made a rope from shopping bags using a giant twisting device made out of bicycle parts
. Then I thought, why do you need to twist it? I think twisting makes sense if you are using a very fibrous material so the fibers can kind of grab together and get intermeshed. But plastic shopping bags aren't really fibrous, so maybe you don't need to bother with the twisting.
So I came up with this way to make a very strong rope. The cool thing about it is you don't need *any* tools to make it.
